  1. Go to your backups. You do backup your system, don't you? YouTube/watch?v=l7-6m2cE6JM

  2. Fix your broken code.
    1. EAs : Don't do per tick that you can do per bar, or on open.
      If you are waiting for a level, don't reevaluate, wait until price reaches it (or a new bar starts and you recalculate.)
      If you are waiting for an order to open or close, only look when OrdersTotal (or MT5 equivalent) has changed.

    2. Indicators: Code it properly so it only recomputes bar zero (after the initial run.)

    3. Or, reduce Tools → Options (control+O) → Charts → Max bars in chart to something reasonable (like 1K.)

Tank you very much! I solved my problem. I changed a property in an EA and the problem was gone.
