Topic: Backloading historical MT4 data
After just about wearing out my home key trying to force data load of symbols across a number of symbols and brokers I ran across this script in a post which will automate the process for you. It's on page 6 filename "ForceLoadHistoricalData_mod.mq4"
If you drop it on an empty chart and it rips through every symbol in your marketwatch window and navigates back to the beginning of history for every timeframe. It takes a bit of time but beats the heck out of doing it by hand. In any case I figured it might help others out as well.
