What the research says, the math behind every loss, and the rules that keep your account alive long enough for your edge to work.
Research that tracked real day traders' accounts keeps finding the same thing: the majority lose money, and very few stay consistently profitable year after year. A strategy can only work if you are still in the game long enough to use it. That is the job of risk management.
Your first job is not to make money. It is to protect the account so your edge has time to show up.
You cannot manage risk you have not priced. NQ and MNQ move in the same 0.25-point ticks. The only difference is the dollar value of each move.
| Contract | Multiplier | Tick size | Per tick | Per point | A 20-point stop |
|---|---|---|---|---|---|
| NQ (E-mini Nasdaq-100) | $20 × index | 0.25 pts | $5.00 | $20 | $400 |
| MNQ (Micro E-mini) | $2 × index | 0.25 pts | $0.50 | $2 | $40 |
Micros let you size in smaller steps. That makes them the easier tool for matching a stop loss to a fixed dollar risk.

CME Group's education course says to decide your size before you enter, using two inputs: where your stop goes and how much of your account you are willing to lose. Its guidance for new traders is 1% to 3% of the account per trade.
Dollar risk is $500. Each MNQ contract risks 20 × $2 = $40. $500 ÷ $40 = 12.5, so you round down to 12 contracts, which risks $480.
Each NQ contract risks 20 × $20 = $400. $500 ÷ $400 = 1.25, so you round down to 1 contract, which risks $400.
Round contracts down. Place the stop where your idea is proven wrong, then let the size adjust to it.
Pick the size first and then squeeze the stop tighter to make the dollars fit. CME notes a stop should not sit where normal price movement can easily hit it.
Starting small is smart. But once you are advanced, risking so little can hinder you, because it starts to feel like you are trading for nothing. As your skill and your results grow, your risk can grow with them, inside your limits.

Every drawdown needs a bigger percentage gain to recover, because you are growing a smaller balance. This is plain arithmetic: gain needed = loss ÷ (100% − loss).
Chance of hitting at least one losing streak of this length somewhere in 100 trades:
| Your win rate | 5 losses in a row | 6 in a row | 8 in a row |
|---|---|---|---|
| 50% | 81% | 55% | 17% |
| 40% | 98% | 87% | 49% |
Calculated by simulating 100,000 runs of 100 independent trades at each win rate.
win rate to break even
win rate to break even
win rate to break even
Break-even win rate = risk ÷ (risk + reward), before commissions and slippage, which push it higher.
At 1% risk, ten losses in a row costs about 10%. At 10% risk, the same streak costs about 65%.
CME's trade plan lesson lists a maximum loss per trade and a maximum loss per day as parts of every plan. Prop firms enforce the same idea automatically.
Your position sizing number from section 03. It never changes mid-trade.
When you hit it, the platform is closed for the day. Write the number down before the open.
The lowest balance you will allow before you stop and review your trading.
It starts at $2,000 below a 50K account, $3,000 on 100K and $4,500 on 150K. It trails up with your end-of-day balance and never moves down. It counts open, unrealized P&L, and touching it liquidates the account immediately with no exceptions.

The CFTC warns that futures are leveraged, so small price moves can swing your balance hard in either direction. Losses can be larger than your initial margin, and you are responsible for covering the difference.
It turns into a market order when triggered. In fast markets and around news, the fill can land past your stop. That gap is slippage.
It only fills at your limit or better. If price runs through it, you can stay in a losing trade with no exit.
NinjaTrader's guidance is that in fast or news-driven markets, some slippage costs less than an exit that never fills.

Kahneman and Tversky's research on loss aversion found that people treat a loss as roughly twice as large as an equal gain. In trading, that pull shows up as moving a stop, holding a loser, or sizing up to win it back.
Bracket orders placed at entry. A daily loss limit decided before the open. A fixed size you calculated while calm.
Widening a stop, adding to a loser, or doubling size on the next trade to get back to even.
Trading is 20% strategy and 80% psychology.

Answer honestly. There are no right answers, only true ones. Your results suggest how much to risk, which model fits you, and what to work on so your risk plan fits your personality and your mental health.
This is not financial advice. Your result is a suggestion to help you understand yourself, and you can still choose what works for you.
