Martingale: doubling down on losses
A martingale EA increases its lot size after every loss — classically doubling it — so that one winning trade recovers the whole losing streak. The equity curve looks beautifully smooth, right up until the streak runs long enough that the next position is too big for the account.
The arithmetic is brutal. Starting at 0.01 lots, seven losses in a row means positions of 0.01, 0.02, 0.04, 0.08, 0.16, 0.32, 0.64 — 1.27 lots in total to recover a string of 0.01-lot trades. On gold, where a single session can move tens of dollars, that streak is not rare.
Grid: adding positions as price moves away
A grid EA opens another position every time price moves a fixed distance against the last one, then closes the whole set when price comes back. Many grids also multiply the lot size at each level, which makes them a grid-martingale hybrid. With no limit on the number of levels, exposure keeps growing for as long as the move continues — and gold is famous for long, one-directional trends.
Capped basket management
Basket management also holds more than one position at a time, but with two hard limits: a fixed maximum number of legs and no lot multiplier. In the words of the Philippe Calibre 79 product page: It utilizes a built-in basket closure mechanism to manage floating positions, avoiding the use of unmanaged lot multipliers.
- Basket Management: Automatically pairs negative positions with larger positive positions to exit the market cycle at a designated target level.
- Dynamic Trailing: Features an optional percentage-based trailing exit to manage the basket closure.
- Daily Equity Controller: Includes optional inputs to halt trading for the remainder of the day if a specific daily percentage limit is reached.
- Maximum Open Legs: Limits the permitted number of concurrent positions per cycle. Every official preset sets it to two.
| Martingale | Grid | Capped basket | |
|---|---|---|---|
| Lot size after a loss | Multiplied (often ×2) | Often multiplied per level | Unchanged — set by the risk profile |
| Number of open positions | One, growing in size | Unlimited, one per grid step | Hard cap (2 in Calibre 79 presets) |
| How exposure grows | Exponentially with a losing streak | With every step price moves against it | Bounded by leg cap × lot size |
| Typical equity curve | Smooth, then a cliff | Smooth, then a cliff in trends | Dips while a basket floats; losing cycles still happen |
| What breaks it | A long losing streak | A strong one-way move | Floating loss beyond your drawdown tolerance |
“No martingale” does not mean “no drawdown”
How to check any gold EA before you buy
- Read the inputs, not the headline. Parameters named multiplier, lot exponent, grid step or max orders tell you how the EA really sizes and adds positions — and whether there is a cap.
- Compare equity and balance drawdown on the live signal. A huge gap means large floating losses are being carried.
- Check “max deposit load” on the MQL5 signal page: the peak share of the account used as margin. Martingale and grid systems often show spikes here.
- Backtest through a strong trend with real ticks — calm ranges flatter every averaging system. The free demo guide shows how.
- Ignore win rate on its own. Averaging systems win often by design; the size of the worst loss is what matters.
Where Philippe Calibre 79 fits
Philippe Calibre 79 is a basket system with a capped number of legs and no unmanaged lot multipliers, plus filters for high-impact news, extreme ATR expansion and low-liquidity holiday periods. It is not a one-trade-with-a-stop-loss system, and it does carry floating drawdown — so size your account from the live equity drawdown and pick a risk profile you can sit through.
