You can change Box size (in pips) and Reversal amount (in boxes). Any timeframe, any pair.
By default: green mean "X" and red "O".
For Better viewing use line graph and change from chart properties (F8) line graph color to "None".
Bug report: If you refresh chart by adding older bars, then you need reload indicator (i.e switch timeframe and back). If anybody knows solution, you are welcome.
