Grid / Martingale Calculator

Grid and martingale systems look safe because most trades close in profit. What kills accounts is the fat tail — the one trade that opens 6, 8, 12 more positions before price finally reverses. This tool shows you exactly what that scenario costs.

Drawdown grows non-linearly.Doubling the lot at every level (a “classic” martingale) means each new position drags the whole basket further underwater. By level 8 with a 2× multiplier and a 300-point step, the open floating loss is not double or triple level-4's — it's an order of magnitude larger. The DD column makes the geometric growth visible; the chart makes it unforgettable.

Breakeven distance and basket TP.Every added level shifts the lot-weighted average entry closer to the current price. That's why the basket TP gets easier to hit — but only if you survive long enough to see it. The Basket Profit at TP row shows how little you actually earn for taking on all that drawdown risk.

Why level caps matter.The single most important input on this page is Max Levels. A grid without a hard cap is not a strategy — it's a bet that the market will always turn before your equity runs out. Setting a real level limit forces the EA to close and take the loss, which is what a disciplined trader would do manually. If the DD % at your maximum level is uncomfortable, you already have your answer: shrink the multiplier, widen the step, or move the maximum down.

Cent accounts.Selecting Cent doesn't change the math — it changes the currency. A cent account with $100,000 is really $1,000 in USD terms, so the DD figures should be read in cents. The risk grade uses % of balance either way.

Read the risk grade like a smoke alarm.SAFE (<15%) means the worst-case drawdown is survivable. MODERATE (<30%) means one bad news candle blows through your comfort zone. AGGRESSIVE (<60%) means you're one gap away from re-mortgaging your account. ACCOUNT KILLER (≥60%) is exactly what it sounds like.
