How It Works

Two independent code paths keep entry signals separate from grid continuation, eliminating the grid-freeze bug found in earlier martingale systems.

📍

Midpoint Signal

Each bar, the EA computes the midpoint of the previous candle's high and low. If price is above the midpoint it signals BUY; below signals SELL. No external indicators required.

🅐

Path A — New Basket

When no positions are open, a new L1 trade is placed only when the bar signal matches the allowed direction. The starting lot resets to the base lot after an easy win.

🅑

Path B — Grid Continuation

Once a basket is open, additional levels (L2, L3…) are added whenever price moves against the basket by at least ATR × multiplier. This path is unconditional — it runs every bar regardless of the signal.

🔄

Direction Flip

When a basket reaches the max grid level it is counted as a "hard basket". After a configurable number of hard baskets, the EA flips direction (BUY → SELL or SELL → BUY) and scales the next lot size.

✅

Basket Take Profit

All positions in the basket are closed together when their combined floating profit reaches the target in pips. This aggregates all levels into a single exit event.

🛡

Equity Guard

An optional emergency stop closes all positions if the account drawdown exceeds a percentage threshold, protecting against extreme adverse market conditions.
