When this is a programming or MT4 question, I don't know. I dropped about 30 hours of data. Only M1. I am an M1 trader so I would like to have it for backtesting. I was told to press F2, highlight the currency and TF, delete all and start a new chart. I did so and it worked, I only have ~ 2 days worth of information. By holding down the arrow key, I can go back but that's quite slow. Is there anyway I can speed this process up?
