I am trading using Meta Trader 4 on Android. I have trouble deleting trend lines, fibo and other tools. Instant removal is possible, but after turning it off and on again, the trend line reappears, sometimes it doesn't turn off and only changes chart, the trend line that was already deleted reappears in the intended pair, it's like it's already saved on the phone.
Maybe there's a trick to be able to delete trend lines, fibo, and other tools. Please help me, thank you.
