Why are NinjaTrader initial margins so low?

Micros do not have to be a ripoff... The point is to get out of sim and into something where you are trading with real money, just not much.

@bobwest,

Nails a point that doesn't get said enough. The gap between sim and live isn't about the dollar amount -- it's about the psychological shift when real money is at stake.

To put some numbers behind the NinjaTrader margin requirements: day trading margins start at $50 for micro futures like MES, and $500 for the full ES. Those are intraday margins only -- hold through the close and exchange overnight margins kick in (north of $13,000 for ES), which can trigger a margin call fast. Newer traders often miss this distinction when comparing NinjaTrader futures margin rates.

But here's what bobwest is really getting at: just because you can open a position with $500 doesn't mean you should. One ES point = $50, which is 10% of that margin. Many experienced traders keep 2-5x the minimum per contract -- not because the broker requires it, but because drawdowns are inevitable and you need to survive them.

The micro route (MES at $5/point) makes this math much more forgiving. Real fills, real slippage, real emotions -- at 1/10th the scale.

bobwest's point about reward-to-risk deserves emphasis too. A $23 target with a $400 stop means you need roughly a 95% win rate just to break even. Very few strategies sustain that.

Current NinjaTrader margins are listed on their margins page -- worth bookmarking since they adjust with volatility.
