Eligible NinjaTrader Group customers can now trade MIAX’s Tini Bloomberg 500 and Tini Bloomberg 100 index futures, widening retail distribution for the exchange’s US equity derivatives. The 15 October announcement concerns access through NinjaTrader; the contracts themselves began trading earlier in 2026 on MIAX Futures.[1]
The two benchmarks cover different portfolios. B500 represents the 500 largest US companies by market capitalisation. B100 selects 100 highly capitalised companies from technology, healthcare, consumer staples, consumer discretionary and communications, using modified market-capitalisation weighting. A trader comparing the products needs to consider that sector mix alongside contract size.[2][3]
The two Tini contracts available through NinjaTrader
| Feature | Tini B500 | Tini B100 |
|---|---|---|
| Platform symbol | TBX | TBQ |
| Contract multiplier | US$10 × B500 index | US$10 × B100 index |
| Outright minimum tick | 0.10 index point = US$1 | 0.10 index point = US$1 |
| Contract months | March, June, September, December | March, June, September, December |
| Settlement | Cash | Cash |
For an illustrative index level of 5,000, the US$10 multiplier produces US$50,000 of notional exposure. A ten-point futures-price move changes the position’s value by US$100 per contract. These calculations use a hypothetical level; they are neither a current quote nor the margin deposit required to hold the position.[2]
The zero fee applies at the exchange
MIAX advertises free market data and zero exchange fees for retail trading. Its fee schedule defines the retail category as an account in the name of a MIAX-approved retail broker and explicitly bills OCC clearing separately. Broker commissions and other account charges therefore remain separate parts of a customer’s transaction cost.[4][1]
The published trading session runs from 18:00 to 17:00 US Eastern time, Sunday to Friday, with a one-hour daily pause. The small tick and extended session can help traders size and time positions, while the ability to enter and exit efficiently still depends on executable depth and spreads during their chosen session.[3]
MIAX expects further retail brokers to add these contracts during the fourth quarter. NinjaTrader supplies a live distribution channel for that expansion, bringing the products into an existing futures trading workflow.[1]
