Submit Grid Order

Submit a grid strategy order. The grid places buy orders as the price falls and sell orders as it rises, within the [lower_limit_price, upper_limit_price] band anchored to submitted_base_price.

Before using grid trading you must record the strategy risk-disclosure consent once — see Submit Strategy Questionnaire.
