Martingale & Aggressive Position-Sizing After Losses – Strictly Prohibited

Understand the strict prohibition against Martingale and aggressive position-sizing after consecutive losses. This article outlines the rules for calculations and breach triggers.

Updated this week

What is Martingale?

Martingale refers to a trading approach where a trader significantly increases their lot size—typically doubling it—in an attempt to recover previous losses or amplify potential profits.

How do we measure Martingale?

We classify Martingale when a trader doubles their lot size following a losing streak of two or more consecutive trades within a 6-hour window.

How does the rule work?

Once you enter a losing streak, you cannot double your lot size on the trades that follow.

The first trade in the losing streak is used as the reference point.

If the losing streak begins with a 1-lot trade, any increase to 2 lots or more would result in a violation.

Example :

Trade 1: 1.00 lot → Loss (start of losing streak)

Trade 2: 1.00 lot → Loss

Trade 3: 2.00 lots → This is double the initial losing-lot size (1.00), therefore Martingale violation.

Trade 1 was taken at 1.00 lot.

When entering a losing streak, increasing to 2.00 lots (2× the reference size) triggers a Martingale breach.
