tastyfx: US forex accounts, contract sizes, costs, funding and protection

tastyfx separates its US forex service into spread-only Standard, commission-based Zero+ and higher-balance Prime accounts. The important comparison is the price of the same currency exposure, not whether an account advertises a zero spread. Product selection and platform eligibility also change with the account.[1][2]

The three pricing types can coexist, but each account is margined independently. MT5 accounts are opened separately. The main comparison lists tastyfx and MT5 for all three routes, with TradingView for Standard and Prime—not Zero+.[1]

A 0.01 mini EUR/USD contract is one-tenth the exposure of a 0.01 standard contract. That difference matters when setting a cash risk limit: the same stop distance produces different cash gains or losses. Always use the symbol’s own contract definition rather than assuming that every screen’s “lot” means 100,000 units.[5]

On those assumptions, the zero-spread account is not the cheapest. Its USD 10 round-trip commission equals one EUR/USD pip at this size. The actual comparison can change when spreads change; the calculation is a transparent threshold, not a prediction that any quoted floor will be available.

Financing is a charge or credit on the exposure held overnight, not on the deposit alone. Its sign can differ between buying and selling the pair. A funding calculation should use the live direction-specific rate and the actual number of roll days; applying a flat daily percentage to the cash balance would model a different product.[6]

Stops are triggered against the dealer’s executable bid for a sell or ask for a buy. A limit seeks the specified price or better; a triggered instruction may remain active when that price cannot be obtained. The dealer can reject instructions or restrict exposure. These terms do not provide a guaranteed stop-loss price.[9]

The account balance, free margin and amount cleared for payment are different figures. Closing a trade may free margin, but it does not by itself clear a bank-verification hold. The secondary payment report also says card refunds are limited to the amount deposited by that card; profits use an approved bank route.[23]

There is no established per-client excess-insurance policy in the reviewed tastyfx material. The absence of a readable current NFA record here is an evidence limitation, not a finding that the company lacks registration. The sharper protection distinction is the documented one: off-exchange forex is not a SIPC-protected securities account.[21][8]

A telephone dealing route exists, but neither a working number nor a business-continuity provision guarantees execution during a system-wide incident. Check whether an uncertain electronic order was accepted before submitting a replacement.[16][9]

Prime’s public page advertises boosted interest for the first 120 days. The linked December 2025 agreement instead contains an earlier welcome period ending 28 February 2026 and qualifying activity conditions. Those documents do not establish one unambiguous current interest entitlement. Obtain the accepted current schedule before including any interest in a cost comparison; neither 8% on all balances nor passive eligibility is assumed here.[3][4]

Custom FIX/REST interfaces and external automation require prior written consent under the customer agreement. That permission clause does not prove that a public, self-service API is currently available. No native AI trading mandate or fully documented copy-disconnection service was established. Stopping software should not be treated as confirmation that outstanding orders or positions have closed.[9]

The IG US rebrand page says existing accounts and login details continued under tastyfx, with the core technology and trading arrangements retained. This was not a transfer into the separate tastytrade securities account. Corporate relationships and platform branding should be read separately from the company named on the forex agreement.[20][21]

A recurring inactivity charge and a dated deactivation/reactivation schedule were not established from the retrievable official tariff and agreement. ProRealTime’s activity waiver is a software-charge rule, not a substitute answer to either question. The unresolved official withdrawal tariff, current Prime interest terms and specific API access conditions are the material remaining verification points.[13][9]
