After this weekend I found that the tester on more than one broker will not download real ticks and won't even use real tick history already accumulated. Anyone else getting this problem?

How to Clear MT4/MT5 Cache and Speed Up MetaTrader?
Michael Charles Schefe, 2025.11.15 01:05
the most obvious place to go is the ticks and history folders and delete those files. You could also go to mt4/5 settings to change the maximum number of candles you will allow on a chart.
But in my experience, when I delete all my backtest and optimiser test data, then mt5 is afresh again. Which is why i tend to keep my terminals that I use for backtests and optimisations -- on a separate terminal from my trading terminal(s). The main folder to delete is Tester -- i just have to remember to recreate this folder again, before i restart the terminal.
another place is logs, there is 2 of these in mt5 folders, 1 in mt5 directory, and the 2nd is in the mql5 folder. just remember to recreate these folders before restarting the terminal.
And if all fails -- ie mt5 continues to be slow, then I copy all my ea and indicators to a new copy of mt5 portable. and delete/uninstall the old slow terminal.
