A timed stored value of money waiting on the lay side

[Gareth1976]

Hi guys

Is it possible to store a value of the money waiting on the lay side 5 seconds ago?

My idea is to say 10 minutes out from start time, watch the "money waiting on the lay side" drop down from 100 to 50, say 1 second ago, then place a trade at the best price. And eventually do the same on the way up.

Would setting a signal as the lay money waiting, then use a signal change condition with a time work?

Ive never tried using signals before so this is a totally new area to me.

Thanks for any advice in advance guys
