I jsut thought of a cool feature that might be helpful.
If the PTL Trader Pair Grid kept track of the High and Low of the Z Score for the day, one could possibly use that info to make risk/reward decisions later in the trading day. For example, yesterday I noticed a pair almost hit my exit level of 0. It was so close to zero at the end of the day, I felt it was best to close the position rather than carry it overnight for very little reward.
just an idea....
