Grid Trading

A grid strategy may place multiple trades at different prices. Risk can increase when the market trends strongly against the open basket.

Martingale Position Sizing

Martingale approaches increase position size after losses. This can accelerate recovery when the market reverses, but it can also accelerate losses when it does not.

Know the Worst-Case Structure

Investors evaluating managed forex accounts should understand maximum open positions, maximum lot exposure and the conditions used to close losing baskets.
