From the FAQ of Histdata they describe their M1 bars time stamped EST without Day Light Savings adjustments and as bid prices.

1. Does convert.c convert the time (with DATE ConvertTime(...)) to UTC or do I have to change the code to do it?

2. According to the manual bid prices have to be converted to ask prices by adding the broker's spread. Is this already considered in convert.c (I can't find it in the #ifdef HISTDATA, but maybe this is only my problem) or do I have to add the spread from AssetFix.csv by code, or is this covered by "Using ask or bid price history has however normally no effect on backtest results"?

Thanks, Sphin
