Clip

CLIP(@,0,10)

This function is often used instead of Truncate Display. Suppose you want to look at the moving average but not its history. Clip the last ten (or some other number) bars to see only that data.

Maximum Per and Minimum Per

 

MAXPER(High(@),BarIx(@,StartOfDay)+1)

MINPER(Low(@),BarIx(@,StartOfDay)+1)

These functions are used with Imoku and trade systems.

They do the same thing as MaxSince and MinSince except here you can directly insert conditions in the formula instead of using parameters.

Bid Volume and Ask Volume

 

@:bidvolume

@:askvolume

These functions are used with TFlow in lieu of VolAsk and VolBid study outputs.

Filter Tick Bate

FilterTickBate(@,1) = bid

FilterTickBate(@,2) = ask

These studies are used to chart the bid and ask and is used most often by spread traders, who chart bid to bid or ask to ask.
