This indicator shows four price histograms when a click event is fired.
Personally, I made it for the check at the time of development, but it was shared.
Updates (30/07/2015):
v 1.01
Eliminated bugs due to the InpCalcTime does not work.
Changed the BinRangeScale from 6 to 4.
v 1.02
A large bug was found. Please use here.
before:
  calc_histgram(lt_vh,lt_vhZO,m30high,m30low,m30vol,offset,limit,InpBinRange*8,lt_period);
  calc_histgram(mt_vh,mt_vhZO,m30high,m30low,m30vol,offset,limit,InpBinRange*8,mt_period);
after:
  calc_histgram(lt_vh,lt_vhZO,m30high,m30low,m30vol,offset,limit,InpBinRange*BinRangeScale,lt_period);
  calc_histgram(mt_vh,mt_vhZO,m30high,m30low,m30vol,offset,limit,InpBinRange*BinRangeScale,mt_period);
...it is my stupid error.
Display:
Red — 1-day histogram (use M5 timeframe).
Gold — short term histogram (use M5 timeframe).
Pink — medium term histogram (use M30 timeframe).
