Grid trading — Placing layered orders at intervals around price to accumulate positions as the market moves, commonly restricted alongside averaging and martingale.
How grid trading works in prop trading
A grid system places buy and sell orders at fixed intervals and accumulates exposure as price moves through them. In a range it produces steady small gains; in a trend it produces a growing position against the move, which is functionally averaging down with more steps. That end state is why firms treat grids the same way they treat martingale.
Grid systems also collide with mechanical rules independently of the strategy prohibition. Accumulated legs breach contract caps easily, and on an equity-trailed drawdown the aggregate unrealised loss of an open grid is measured continuously. Many grid accounts fail on the position limit before anyone reviews the strategy.
Key points
- Restricted at most firms in the same clause as martingale and averaging down.
- Accumulating legs breach contract caps quickly, independently of any strategy rule.
- Trending markets turn a grid into a large position against the move.
- Typically implemented as a bot, so the automation rules apply on top.
Also known as
- grid strategy
- grid bot
- layered orders
Frequently asked questions
Can you use a grid bot with a prop firm?
Rarely. Even at firms permitting automation, grid systems usually fall under the same prohibition as martingale and averaging down. Where they are not explicitly banned, the contract cap and drawdown mechanics tend to end the account first.
Is grid trading the same as DCA?
They overlap. Both accumulate exposure as price moves against the position. A grid does it through pre-placed orders at fixed intervals; DCA usually means discretionary additions. Firms generally treat them under one rule.
