Dear Sir or Madam:
I met a difficult problem when using MQL4 programming. I will deeply appreciate if you can offer me some suggestion, clue, or a solution. Thanks a lot.
The problem is: how to update realtime and historic data with a MQL4 program. I need the latest data of at least 100 bars, all timeframe, all pairs(symbol), to monitor the market environment and locate the trading signal.
I have tried RefreshRates( ), but it respond like “zero divide”. I believed it is because there is not enough realtime data.
Thanks again! My email: Simonhua2003@yahoo.com.cn
