Martingale and grid EAs
A martingale EA increases position size after each losing step — often doubling — so that a small move back recovers everything. A grid EA opens new positions at fixed distances as price moves away. Both produce smooth equity curves most of the time, because most moves do come back.
- Exposure grows geometrically: a few steps of doubling turn one lot into dozens.
- Positions often have no stop loss, because the system is waiting for price to return.
- One sustained trend can wipe out months of gains — or the whole account — in a single session.
A structured hedge
A structured hedge places a single opposite position behind the primary trade, sized in advance. If the market reverses, the hedge gains while the primary loses, so the loss is capped. Exposure has a known maximum instead of growing with every step against you.
| Martingale / grid | Structured hedge (GoldBot MultiRange) | |
|---|---|---|
| Reaction to a loss | Adds bigger positions | One pre-sized opposite position |
| Maximum exposure | Unbounded as it keeps adding | Hedge capped at 5× the first lot |
| Stop loss | Often none | Fixed stop loss on every trade |
| Failure mode | Account-level wipe-out in a trend | A defined, capped loss |
What to check before running any gold EA
- Does every trade have a fixed stop loss?
- Is there a hard cap on how large total exposure can get?
- Does it avoid bank holidays and other thin-liquidity sessions?
- Can you control sizing — fixed lot or a percentage of the account?
- Is the licence tied to your account, or is it a shared file that anyone can copy?
