What Is Grid Trading?
A grid strategy opens positions at fixed price intervals and closes them together at a profit target. How grids work, why they win often, how they lose, and the numbers that decide which.

Grid trading places positions at fixed price intervals — the grid — and closes them together once the group, or basket, reaches a profit target. If price moves against the first position, the grid adds another at the next level, which lowers the basket's average entry so a smaller move back is enough to close everything in profit. That is why grids win often. It is also why they lose big: when price keeps going instead of coming back, every new level adds exposure to a losing basket.
| Level | Lots | Relative size | Price moved | Lots open | Floating loss as it opens |
|---|---|---|---|---|---|
| 1 | 0.01 | $0.00 | 0.01 | — | |
| 2 | 0.01 | $5.00 | 0.02 | −$5 | |
| 3 | 0.01 | $10.00 | 0.03 | −$15 | |
| 4 | 0.01 | $15.00 | 0.04 | −$30 | |
| 5 | 0.01 | $20.00 | 0.05 | −$50 | |
| 6 | 0.01 | $25.00 | 0.06 | −$75 |
How a grid works, step by step
Open the first position
A buy at 3,000.00, for example — on a signal, a filter, or simply at the start.
Price moves against it
At 2,995.00, one grid step ($5) lower, the grid opens a second buy.
The average entry falls
Two equal buys at 3,000 and 2,995 average 2,997.50. Price no longer needs to return to 3,000 — only a little above 2,997.50.
The basket closes together
When the combined profit of all open positions reaches the target, every position closes at once. The grid resets and starts again.
Or it keeps going
If price keeps falling, the grid keeps adding until it reaches its maximum number of positions. From there it can only wait — or be stopped by a risk limit.
The two variants that matter most are how far apart the levels are (grid spacing) and whether each new position is bigger than the last (lot multipliers). Equal lots make a flat grid; growing lots make what is often called a martingale grid — the difference changes the risk profile completely.
Why grids win often
Markets spend much of their time moving back and forth rather than in straight lines. A grid is built to profit from exactly that: each adverse move is met with a new entry, and any retracement closes the basket. On a ranging day a grid can close basket after basket, each for a small profit.
The result is a characteristic record: a high win rate, small wins, and occasional large losses. The equity curve looks smooth for long stretches, then drops. Judging a grid by its win rate is judging it by the part of its behaviour that was never the risk.
How grids lose
A grid loses when price moves further in one direction than the grid can absorb before its risk limit, its margin, or its trader gives up. Three things drive how quickly the loss grows:
- Distance travelled: every open position loses more with every dollar the price moves.
- Positions open: each level adds to the lots losing on that move.
- Size of the late levels: with a multiplier, the last levels hold most of the exposure.
For a flat grid of 0.01 lot every $5, the loss when the sixth level opens is $75; for the same grid with each level doubled, it is $285, and past the eighth level it grows by $255 for every further dollar. Grid trading drawdown explained derives the curve.
A grid compared with a stop-loss trade
The clearest way to see what a grid changes is to put it next to a conventional trade on the same idea — “gold will bounce from here”:
| Single trade with a stop | Grid | |
|---|---|---|
| When wrong by a little | Stopped out: a small, known loss | Adds a level; usually closes in profit on the bounce |
| When wrong by a lot | Same small loss — the stop already closed it | Adds every level; a large loss, bounded only by a risk limit or margin |
| Win rate | Moderate | High |
| Size of losses | Fixed in advance | Grows with the move |
| What decides survival | Position size | Depth, multiplier and the account-level limit |
Neither is free. The stop-loss trader pays with many small losses; the grid trader pays with rare large ones. A grid is a decision to prefer the second kind — which is only sensible if the large ones are capped at a level the account survives.
The parameters that decide the risk
| Parameter | What it controls | Trade-off |
|---|---|---|
| Starting lot | Size of the first position — and, with a multiplier, of every level | Everything scales with it linearly |
| Grid step (spacing) | Distance between entries | Tight: more baskets close, less room before the grid is full. Wide: fewer closes, more room |
| Lot multiplier | How much bigger each level is | Above 1 speeds up recovery and multiplies exposure |
| Maximum positions | How deep the grid goes | Deeper grids survive bigger moves only if the account can carry them |
| Basket target | Profit that closes the basket | Higher targets mean fewer closes and longer exposure |
| Account-level stop | Drawdown at which everything closes | The only parameter that bounds the loss |
Grids on gold
Gold is a popular grid market because it retraces often within its daily range and trades almost 23 hours a day. It is a demanding one because its moves in dollar terms are large and it reacts fast to US data, Federal Reserve decisions and geopolitical shocks — exactly the conditions in which a grid fills its levels quickly. XAUUSD grid trading covers the gold-specific mechanics and considerations.
What makes a grid survivable
- A hard account-level limit that closes everything at a set drawdown, and does not restart on its own.
- Sizing from the worst case: the loss with every level open and price beyond the last one — not from the typical basket.
- Filters that stand aside when a trend is strong or volatility spikes, rather than adding into it.
- Awareness of events: scheduled releases and weekend gaps are the moves grids handle worst.
- Honest testing on tick data over periods that include violent markets. See how to backtest an EA in MT5.
