price range function

[hypertrader]

For the selected number of bars/ticks <<length>> and the number of sub-intervals <<bars>> this small function shows the range of the price movement to the right of the price bars.

Might be helpful for certain strategies....

// length gives the number of intervals/ticks used for calculation
// bars defines the number of bars into which length is divided
// the function divides the data stream of defined <<length>> into <<bars>> sub-intervals
// for each subinterval a bar is drawn to the right of the price bars from low to high
// the part of the bar above close() level is red below green
