Martingale in Trading: An In-Depth Analysis of the Risky Averaging Strategy

Martingale attracts traders with the promise of turning losses into profits. It’s a strategy based on a simple principle: after each loss, increase your next bet until you recover the losses and make a profit. But behind its apparent simplicity lies complex risk mathematics that many traders underestimate.

The Origin of Martingale: From Casinos to Modern Trading

The history of Martingale dates back to 18th-century gambling. French casino players used this system on roulette: if a bet lost, they doubled the amount for the next round. The logic was relentless — with enough money, mathematically, a win would cover all previous losses.

Traders noticed the parallel with financial markets and adapted the method for asset trading. At first glance, the casino principle works here too: if an asset drops, you buy more at a lower price, averaging down your position. When the price bounces back slightly, you close in profit.

How the Martingale Strategy Works in Asset Trading

Practically, applying Martingale in trading looks like this: you open a position at the initial price. If the asset moves against you, instead of closing with a loss, you open a new order with a larger size. This technique is called averaging down.

Example: you bought BTC at $67,500. The price drops to $65,000. Instead of exiting, you open a second order of larger size. Your average position price decreases. If BTC bounces to $66,000, both positions will be profitable.

The core idea is simple: increasing order size lowers the average entry price. Even a small price rebound allows you to close all orders profitably. But this only works if your funds don’t run out before the price turns around.

Mathematical Calculation of Order Sizes in Martingale

The size of the next order is calculated by the formula:

Next order size = Previous order size × (1 + Martingale percentage / 100)

Suppose you start with $10 and choose a 20% increase per order:

• Order 1: $10
• Order 2: $10 × 1.2 = $12
• Order 3: $12 × 1.2 = $14.40
• Order 4: $14.40 × 1.2 = $17.28
• Order 5: $17.28 × 1.2 = $20.74

Total expenditure: $10 + $12 + $14.40 + $17.28 + $20.74 = $74.42

If your deposit is $100, 5 orders consume 74% of your capital. You have $25.58 left. This is critical: if the price doesn’t reverse at the 6th order, you may run out of money.

With a more aggressive 30% increase over 5 orders, you’ll spend $90.88 out of $100. At 50%, it’s $131.07. It’s clear that as the Martingale percentage increases, the required capital grows exponentially.

Advantages and Critical Risks of Martingale

What attracts traders to Martingale:

Fast recovery of losses — any price dip immediately turns the position into a profit thanks to averaging down. No need for precise reversal prediction — you gradually “catch up” from below. Psychological comfort — the illusion of control provides relief after the first loss.

Critical risks:

Deposit depletion — the main enemy of Martingale. If the price keeps falling, each new order requires more money. With a 20% increase, by the 7th order, you need $89.09; by the 8th, $106.91. At this point, a $100 deposit is exhausted. Psychological pressure grows with each loss — irrational decisions may follow. Prolonged decline without reversals turns Martingale into a disaster — the price can fall for months, and no deposit will save you.

Rules for Applying Martingale: Step-by-Step Guide

If you decide to use Martingale, follow these rules:

1. Choose the minimal increase percentage. Optimal — 10-15%. This allows more orders before your deposit runs out.

2. Calculate your order limit in advance. Determine how many orders your deposit can support. Use this number as your maximum.

3. Keep a capital reserve. Don’t invest your entire deposit in the first order. Starting with 100% of your capital in one trade leaves no room for additional orders.

4. Add entry filters. Don’t average down during a strong downtrend. If the chart shows a powerful downward move without signs of reversal, Martingale is more likely to lead to ruin than profit.

5. Set a psychological stop-loss. If you open 5-6 orders and they’re all in loss, close the position. There’s no guarantee the price will reverse at the 7th order.

When Does Martingale Become a Dangerous Tool?

Martingale is most dangerous in volatile markets with long trends. On BTC or other cryptocurrencies, where prices can fall for weeks, it’s a self-destructive weapon. In calmer markets (blue-chip stocks, traditional Forex pairs), Martingale works more often but still requires experience.

Beginners are advised to avoid Martingale altogether. This strategy demands cold-blooded discipline, mathematical precision, and awareness of your limits. A small mistake or emotional decision can wipe out your entire deposit.

Summary: When Does Martingale Work and When Does It Not?

Martingale is not a strategy but an averaging tool that can work if certain conditions are met. The key condition: the price must reverse before your funds run out. On short timeframes and stable markets, this is possible. On long-term trends, it’s almost impossible.

The recommended increase size for experienced traders is 10-20%. For beginners, it’s better to skip Martingale and practice less risky strategies. Remember: Martingale is a way to turn a small loss into a catastrophe if you give in to emotions and calculations don’t align.

Trade consciously, manage risks mathematically, and avoid psychological errors. And remember — the money you can afford to lose with Martingale should be the money you’re willing to lose entirely.
