Many traders have dabbled in the world of Expert Advisors (EAs), particularly those built on the martingale strategy. The VR Overturn EA is designed to let you explore classic martingale principles alongside the intriguing anti-martingale technique.

What sets this EA apart is its straightforward code, which is well-commented, making it easy for traders to understand and tweak as needed.

Trading with Martingale

If a trade closes with Take Profit → open a new position with the starting lot in the same direction;
If a trade closes with Stop Loss → open a new position with an increased lot in the opposite direction.

Trading with Anti-Martingale

If a trade closes with Take Profit → open a new position with an increased lot in the same direction;
If a trade closes with Stop Loss → revert to opening a new position with the starting lot in the opposite direction.

Understanding the Martingale System

With this strategy, you begin trading with a set minimum lot size. If a trade hits a stop loss, you'll increase the lot size for the next trade, aiming to recover previous losses with a profit when the next trade hits take profit. For instance, you might follow a progression like: 0.01, 0.02, 0.04, 0.08, 0.16, 0.32, 0.64, and so forth.

If you maintain this sequence, your total profit could match what you'd earn from a single trade with the minimum lot. Once a trade closes in the green, you reset to the minimum lot.

While the martingale strategy doesn’t inherently give you an edge, it can help redistribute profits. You may frequently see small gains, but watch out—losses can stack up quickly.

Understanding the Anti-Martingale System

In contrast to martingale, the anti-martingale approach focuses on increasing lot sizes when you're in profit. You start with the minimum lot size and, if a trade closes profitably, you ramp up the lot size by two or more times. If you hit a stop loss, though, it’s back to the starting lot.

Establish clear limits on how much you can increase your lot size, and know when to revert to the initial lot. For example, you might decide on a maximum of three successive lot size increases: 0.01, 0.02, 0.05.
