Remove pending order once TP is reached. (simple)

Hi. I trade manually on breakout strategy. I usually have buy stop and sell stop. I want a cBot to help remove a pending order once TP of a trade is it. For example. Buy stop gold 1200 tp 1210. Sell stop gold 1195 to 1180 Gold came to 1195, sell stop is filled. Then gold went all the way down to 1180. (TP is hit) I want pending buy stop order to be canceled. Could anyone help me with this? I think it should be pretty straightforward. But I don't know about coding. Thanks.
