Remember price of O2.5 goals at 7am and if drifted at 5 mins lay the selection

I'm trying to incorporate the following into a trigger that remembers the back price of the the over 2.5 goals market at 7am for matches that I have selected and if the price has drifted by at least 1 tick at 5 mins prior to kick-off, to then proceed with the remainder of the strategy, which in my instance is to lay it in the 0ver 0.5 First Half Goals market. Sounds simple enough but I am struggling to implement this. 

Any help appreciated. 

Thanks

Hi
Give this trigger a try. I've put in several safety checks to make sure the variable for 7am price is correctly set. Obviously you will need to be monitoring both markets. Have only tested this briefly so please test carefully in test mode before using real funds.
