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.

• Red — 1-day histogram (use M5 timeframe).
