[trades4x]

BarBuilder is ot returning correct OHLC values for ES futures, ES price is in the range of 2860 - 2890 on a given day but the  values of OHLC are returnning as:

Hi trades4x,
Bookmap consumes prices in pips (or ticks, interchangeable in this context). If the pips for this symbol is 0.25 the 2860-2890 range becomes 11440-11560
(2860/0.25 = 11440...).
To get regular prices you've got to multiply prices by pips.
You can get pips for this symbol from the InstrumentInfo object in the initialize method.
Multiply every value you get from Bar by pips and you'll have regular prices.

thanks so much
