I probably won't be able to resuscitate since I no longer have TS8.

If I recall correctly, the frac function essentially rounds the band value up or down (down for the upperband, up for the lowerband to return a value in line with the tick values), s you could use other language in TS to get the same result without using that function.

The picperiod was a function I wrote so that all indicators and strategies would share the same start and lunch and end times without having to change them separately. So you could just insert a different input such as TimeZone1, TimeZone2 etc. instead of using this function.

I running this strategy in demo mode on tradestation but in the last period equity go down. Are there changes to apply?
