Cancel pending order based on price being violated

Hello,

How to set-up an OCA on a pending order

Ex: Pending Order (Open Position for BS) = BTO on @ESZ0 at 1110. Pending Order (TP) = BTC on @ESZ0 at 1113.

Pending Order (SL) = STC on @ESZ0 at 1100.

I would like to cancel the pending trade if the price goes below a certain price before the actual trade is executed. How do I do an OCA for this to cancel the entire trade? [LINKSYSTEM_52830244]
