All five risk models are one strategy at five different risk levels. The trades are identical, governed by the same rules: a maximum of two trades a day, stopping after the first daily win. What changes is position size, and with it both the profit and the drawdown.
A risk model is the dollar amount you risk per trade. It is the one setting you choose:
The strategy divides your dollar amount by what the stop costs on one contract. A tighter stop means more contracts; a wider stop means fewer.
Built-in risk filters do the rest: the strategy will not take a trade that risks more than $400 per contract, on any model. The limit is locked in the code; it is not an adjustable setting. What it protects, and what it costs, has its own section further down the page.
There is also a floor: when a setup is valid, the strategy always trades at least one contract. On the $200 and $300 models, a wide stop can make that single contract cost more than the risk per trade you set. The example below shows how, and the $400-per-contract limit is the ceiling.

Across the full seven years, every stop stayed under the $400 limit. That is why the $200 and $300 models share the same largest single loss, $381. From the $400 model up, losses track the setting: the $400 model's largest single loss was $410.
Even though the $200 and $300 models can lose more than their set risk per trade on a single trade, they still produce the lowest overall drawdown. That lower drawdown is essential for smaller accounts and for prop firm accounts still in the early trailing drawdown phase, where every dollar of buffer matters.
Higher risk models increase both return potential and drawdown. There is no optimal setting, only alignment with your account size, risk tolerance, and prop firm rules.
Why these five models. The models are position sizes, not tuned parameters. The strategy logic is identical on every one; the only thing that changes is how many contracts a given stop allows. The risk is set in dollars rather than a fixed number of contracts because dollars keep the risk consistent. With fixed contracts, the same position risks $100 on a tight stop one day and $400 on a wide stop the next; the exposure swings with the market. A fixed dollar amount sizes each trade to its stop, so every trade carries roughly the same risk, whatever the volatility. $200 is the smallest model because of the one-contract floor: below it, the floor keeps the risk and gives away the return. And $800 is the largest model we publish because the largest common prop accounts, 250K, carry a trailing drawdown around $6,500: the $800 model's worst historical drawdown of -$5,374 is the most we would run against that limit and still leave real room. You can size above it. We would not.
You are also free to test any value in between, free, in NinjaTrader. You will find settings that backtest slightly better than the published models, and neighbors that backtest slightly worse. That is contract rounding and sequence luck, not a better strategy.
This is backtested data, not a live track record.
The risk framework at the end of the dashboard sizes each model against account balances and prop firm drawdown limits, and the Trade Management System on the Strategy page explains the sizing in full.
