DMM FX is the OTC currency service of DMM.com Securities in Japan. Normal, Mini and Large quotations sit inside the FX service, while DMM CFD, TOSSY and DMM Stocks require attention to their own account rules. One distinctive feature is the ability to pledge eligible Japanese securities as FX collateral, which introduces a separate cash-shortfall and forced-share-sale process.[6][28]

Normal, Mini and Large FX instruments
Sections ↑Currency formats within DMM FX
| Format | One lot | Maximum per ordinary order |
|---|---|---|
| Normal: 23 currency pairs | 10,000 base-currency units | 100 lots = 1 million base units.Source 6 |
| Mini: USD, EUR, GBP, AUD against JPY | 1,000 base-currency units | 100 lots = 100,000 base units.Source 7 |
| Large: USD, EUR, GBP, AUD against JPY | 10,000 base-currency units | 200 lots = 2 million base units.Source 7 |
Limits beyond the size of one trade
| Control | Published treatment |
|---|---|
| Daily USD/JPY openings | Normal USD/JPY and USD/JPY Mini each have a 10,000-lot daily new-volume limit under their own lot size. Filled openings, including those already closed, and live new limit/stop orders count.Source 8 |
| Other instruments | The FAQ does not set the same daily opening-volume cap for other pairs; per-order and holding limits remain.Source 8 |
| Ticket count | At most 1,000 open-position and live opening-order tickets combined.Source 8 |
| Aggregate holding cap | 10,000 weighted lots. ZAR/JPY, MXN/JPY, TRY/JPY and Mini positions count at one-tenth their actual lots for this aggregate test.Source 8 |
| Pair-specific ceiling | USD/JPY and EUR/USD: 5,000 normal lots; EUR/JPY, GBP/JPY and AUD/JPY: 3,000. The full schedule contains other limits.Source 6 |
Advertised spreads and costs
Sections ↑These normal-pair figures come from the broker’s spread table dated 9 October 2026. The core window runs 09:00–05:00 the following day, JST. Spreads are fixed in principle with exceptions; the outside-window ranges are not guaranteed maximums. Mini and Large instruments have no fixed reference spread in this schedule.[9]
Selected current normal-pair spreads
Account charges, funding threshold and rewards
| Item | Published treatment |
|---|---|
| Initial deposit | No required initial funding amount. Sufficient margin is needed before a trade can be placed.Source 11 |
| Execution and account management | DMM FX/CFD ordinary dealing and account-management charges are zero; spread and financing costs remain.Source 2 |
| Trading-reward cash exchange | From 1,000 points, at JPY 1 per point, subject to the service’s exchange rules.Source 63 |
| Reward scope | FX and CFD can earn points, but the FX ranking system is specific to FX; eligibility depends on the current program.Source 64 |
FX swap accrual and cash transfer
| Step | How it affects the account |
|---|---|
| Rollover | Holding through the business-day rollover creates the applicable swap credit/debit. Holidays can change the number of accrued days.Source 19 |
| Realising only swap | The supported PLUS, STANDARD and mobile FX tools permit swap transfer without closing the currency position.Source 20 |
| Margin effect | Swap transfer moves the amount into cash balance, but equity already reflects the accrued swap; the transfer itself does not increase margin equity.Source 21 |
| Continuing exposure | The position still carries market and future swap risk after accrued swap is transferred.Source 19 |
Margin, loss cut and the separate daily call
Sections ↑FX margin controls
| Measure | Published rule |
|---|---|
| Retail leverage | Maximum 25:1: minimum margin is 4% of trade value.Source 2 |
| Corporate leverage | The higher of 4% and the pair’s weekly FFAJ risk ratio determines required margin; the brand’s maximum remains 25:1.Source 2 |
| Hedging | Both buy and sell legs require margin, and both can carry spread/swap expense.Source 3 |
| Margin ratio | Net assets minus reserved opening-order margin, divided by required position margin, multiplied by 100.Source 3 |
| Intraday loss cut | At 50% margin ratio or below, all positions become subject to forced closure.Source 22 |
| Execution sequence | Unfilled orders are cancelled and open positions are closed without a required advance warning.Source 23 |
| Loss limit | Deposited funds are not an absolute loss cap; the FAQ says additional money can be owed after closure.Source 24 |
An FX additional-margin call follows its own clock
| Stage | Required action or consequence |
|---|---|
| Daily test | A margin ratio below 100% at the daily closing assessment generates a call. The account display may take about 30 minutes after rollover to reflect it.Source 10 |
| Cure | Deposit the missing margin or close sufficient positions. Market recovery alone does not erase the already-issued requirement.Source 25 |
| FX deadline | The ordinary deadline is 04:59 JST on the next trading business day, followed by margin-cut liquidation at 05:00 if uncleared.Source 26 |
| Weekend example | A call arising at Saturday’s close has the following Tuesday 04:59 deadline under the published ordinary-week example. Holiday notices can change deadlines.Source 27 |
Using Japanese shares as FX collateral
Sections ↑The stock-collateral service
| Question | Published treatment |
|---|---|
| Collateral value | Eligible securities held through DMM Stocks are valued at 70% of the preceding Japanese stock-market closing price for FX collateral.Source 28 |
| Eligible assets | Approved domestic listed shares, ETFs, REITs and ETNs; NISA holdings, US shares and broker-designated ineligible securities are excluded.Source 29 |
| Cash-free opening | The service can support FX margin without first selling eligible shares; this does not turn the shares into immediately available cash for every obligation.Source 28 |
| Issued margin call | A new share-transfer reservation after the call cannot arrive in time for the FX 04:59 cure deadline.Source 30 |
| Selling pledged stock | Sale is possible; collateral valuation continues until the sale proceeds are credited under the service’s settlement process.Source 32 |
Pledged shares can be sold to cover a deficit
| Stage | Published rule |
|---|---|
| Morning assessment | An FX account using pledged securities is checked for a net-asset shortfall at each FX market opening.Source 31 |
| Payment deadline | The shortfall must be resolved by 15:00 JST that day.Source 31 |
| Forced securities sale | If still unresolved at 07:30 on the following Japanese stock-market business day, all shares transferred into the FX account can be forcibly sold.Source 31 |
Trading hours and order behaviour
Sections ↑FX session times in JST
| Season | Monday | Tuesday–Friday |
|---|---|---|
| US daylight saving | 07:00–next 05:59 | Tuesday–Thursday 06:00–next 05:59; Friday 06:00–Saturday 05:50.Source 10 |
| US standard time | 07:00–next 06:59 | Tuesday–Thursday 07:00–next 06:59; Friday 07:00–Saturday 06:50.Source 10 |
| Saturday maintenance | 12:00–18:00 | No tool login, order operation or quick deposit during this maintenance window.Source 10 |
Order controls and platform exceptions
| Control | Published behaviour |
|---|---|
| Order types | Instant, limit, stop, IFD, OCO and IFD-OCO are documented. Opening market orders in the separately labelled market-order mode are confined to the DMM Stocks app’s embedded FX tool.Source 33 |
| Order duration | Day, week, unlimited or specified date, subject to the permitted order type.Source 34 |
| FIFO setting | A trade in the opposite direction can close the oldest open position when FIFO is on; when off, the opening/closing designation matters.Source 35 |
| Slippage tolerance | A tolerance can reject a quote outside the selected range, including a favourable move beyond that range.Source 36 |
| Stops | A stop trigger is not a guaranteed fill price; rapid moves can produce a worse execution.Source 37 |
| Simultaneous exits | Supported tools can attach profit-taking/loss-cutting instructions to an opening trade; the DMM Stocks app’s embedded FX/CFD tools omit this feature.Source 38 |
The current FX agreement prohibits external automated dealing software and non-approved trading tools. It also restricts repeated orders within short periods or at an unreasonable frequency, excessive activity in thin markets and conduct that overloads the system. These clauses matter before treating the account as suitable for an automated or high-frequency strategy.[3]
Deposits, withdrawals and transfers
Sections ↑JPY deposit mechanics
| Method | Published condition |
|---|---|
| Quick deposit | JPY 5,000 minimum; each payment must be below JPY 100 million. The broker pays the quick-deposit transfer charge.Source 12Source 13 |
| Ordinary bank transfer | Use the allocated deposit details and exact registered katakana name; the sender pays applicable bank charges. Unmatched remitters can delay allocation.Source 14 |
| Delayed name confirmation | Corporate deposits and unresolved individual-name matches arriving after 15:00 or on a non-bank day are processed after checks on the next bank business morning.Source 14 |
| Funding currency | DMM FX collateral cash is JPY; a securities USD settlement balance is a different product facility.Source 6 |
Getting money out
| Item | Published condition |
|---|---|
| JPY withdrawal minimum | JPY 2,000 minimum, with a full-balance exception below that figure; no published maximum withdrawal amount.Source 16 |
| Before weekday 15:00 | Normally paid on the next bank business day.Source 15 |
| Later / non-bank-day request | Normally the second bank business day, using the registered destination and completing the confirmation/authentication flow.Source 17 |
| Broker withdrawal fee | Zero under the published FX/CFD service terms; withdrawing reserves funds and can reduce available margin.Source 6 |
| Inter-service transfer | Cash can move between the registered DMM FX, CFD-Index, CFD-Commodity, DMM Stocks and TOSSY service accounts; product maintenance and settlement conditions affect availability.Source 18 |
DMM CFD: index and commodity subaccounts
Sections ↑Current CFD product coverage
| Account | Exposure | Margin |
|---|---|---|
| DMM CFD-Index | Eight indices: Japan225, US30, Nasdaq100, S&P500, ChinaA50, UK100, Germany40 and Euro50 | 10%, maximum 10:1.Source 51 |
| DMM CFD-Commodity | 14 contracts across precious metals, energy, agriculture and soft commodities | The general overview quotes 5% margin / maximum 20:1; instrument notices can qualify that headline. See the dated orange-juice limitation below.Source 52Source 65 |
| Ownership | 22 OTC derivative instruments across those two accounts | They do not deliver constituent shares, bullion or physical commodities.Source 50 |
The official notices index lists a reposted orange-juice leverage-change announcement dated 9 October 2026. Its detailed terms and effective time could not be retrieved during the 15 October check, so this profile does not treat the general 20:1 overview as a verified current quotation for that contract. Before placing or maintaining an orange-juice position, obtain the current instrument margin and applicable effective time through the official account or support route.[65][52]
Selected CFD lot multipliers
CFD costs, margin clock and cash allocation
| Area | Different CFD condition |
|---|---|
| Financing adjustment | Gold and silver spot can incur daily rollover interest adjustments. The other applicable contracts use futures-roll price adjustments.Source 53 |
| Loss cut | At 50% margin ratio or below, pending orders are cancelled and all positions in the affected CFD account are closed.Source 55 |
| Daily call deadline | For the published CFD rule, cure the daily additional-margin requirement by 22:59 JST; margin cut follows at 23:00. This is a different deadline from DMM FX.Source 54 |
| Commodity funding | Ordinary bank transfers enter CFD-Index first. DMMCFD STANDARD also requires cash to move via an eligible other account for Commodity funding/withdrawal.Source 52 |
| Account and trade fees | No ordinary dealing or account-management charge; contract spreads, adjustments and execution risk remain.Source 51 |
TOSSY and DMM Stocks: separate services
Sections ↑TOSSY multi-asset derivative account
| Area | Published scope |
|---|---|
| Account access | An existing DMM customer still registers the TOSSY service separately.Source 57 |
| Products | Share, FX, crypto, index, commodity and variety exposures through cash-settled derivatives. A TOSSY share position does not create a DMM Stocks cash-share holding.Source 56 |
| Retail leverage | FX 25:1; indices 10:1; share/variety CFDs 5:1; commodities 20:1; crypto CFDs 2:1.Source 58 |
| Margin separation | TOSSY calculates margin and executes loss cuts by asset category. A headline multi-asset account is not evidence of universal cross-margin.Source 59 |
DMM Stocks ownership and financing costs
| Feature | Current published terms |
|---|---|
| Domestic cash shares | Ordinary fees begin at JPY 55; domestic margin execution commission is zero, with interest and other financing expenses. The FX zero-commission term is not a universal cash-share tariff.Source 60 |
| US cash shares | 0.495% including tax per execution, capped USD 22; trades of USD 2.22 or less have zero commission.Source 61 |
| JPY–USD conversion | JPY 0.25 per USD each direction when converting or selecting JPY settlement; separate from US-share execution commission.Source 61 |
| Settlement currency | DMM Stocks supports USD cash balances and a choice of USD or JPY settlement for US shares, with its own currency-exchange facility.Source 62 |
Platforms, demo and account security
Sections ↑Execution and analysis tools
| Tool | Published role |
|---|---|
| DMMFX PLUS / STANDARD | Browser execution platforms; STANDARD is the compact tool name, not a separate account pricing tier.Source 39 |
| DMM FX app | Dedicated mobile dealing; DMMCFD tools and app serve the separate CFD accounts.Source 39 |
| Premium Chart / trade report | Chart analysis and a tool for reviewing the customer’s own recorded trading results.Source 39Source 40 |
| Simultaneous login | Logging into the trading service from another device can invalidate the previous tool session.Source 41 |
| Demo | FX practice on the published web/mobile demo tools lasts three months; expiry occurs under the stated weekend processing rule. Demo credentials and outcomes are separate from live dealing.Source 42 |
| Passkeys | Apply across registered DMM accounts and protect login, withdrawal requests and bank changes. After setup, ordinary password/email login cannot be restored; the emergency backup site still requires the retained login ID and password.Source 43 |
| Notifications | Login and other account-operation notifications support monitoring of account activity.Source 44 |
Client money, staffed support and complaints
Sections ↑FX trust safeguards
| Area | Published arrangement |
|---|---|
| Named trustees | JSF Trust, SMBC Trust Bank and SBI Clearing Trust are listed for FX client-money protection.Source 46 |
| Coverage calculation | The broker calculates the relevant FX cash, valuation P&L and accrued-swap position after the daily close for its trust process.Source 45 |
| Claim route | Client repayment is handled through the beneficiary representative; the customer does not directly demand payment from the trustee bank.Source 47 |
| Scope limit | Trust segregation does not guarantee the value of an FX position or prevent a debt arising from trading losses.Source 24 |
Contact and escalation
| Route | Published details |
|---|---|
| Staffed FX/CFD support | Monday–Friday 08:30–21:00 JST; 0120-961-522 from landlines or 03-4446-4056 from mobile/other lines. Web forms, LINE and chat routes are available.Source 48 |
| Holiday coverage | The service policy includes weekday holidays except 1 January; individual holiday notices can affect operations.Source 49 |
| Formal complaint | DMM.com Securities Compliance Department: 03-3517-3285, weekdays 09:00–17:00 excluding holidays.Source 2 |
| External FX/index-CFD dispute route | FINMAC: 0120-64-5005, weekdays 09:00–17:00 excluding holidays. Commodity CFD complaints use the Japan Commodity Futures Industry Association route.Source 2 |
The core conditions above are translated from Japanese official materials checked on 10 October 2026. The current notices index was additionally reviewed on 15 October; the orange-juice change remains specifically unverified as explained above. These are published service terms; no account opening, trade, withdrawal or support-response test was performed.
