Update Limit Price
You can automatically update the limit price for an order (or all orders) to coincide with the ask, bid, midpoint, closing or last price.
Automatically update the limit price
On the Order menu select Update Limit Prices.
Set update parameters:
Update price for a single order or all current orders.
Set the update parameters for Buy orders and include an offset amount if desired.
Set the update parameters for Sell orders. If you check Mirror image of buy orders, parameters are set reversed from the Buy orders selections. The mirror images of Midpoint, Last and Close would be the negative values for each of these prices.
