As the title suggests. Has anyone else seen this? I can create a set-up (on a live trading bot), save the set-up as set file, go into the tester, load that same set file and I find random things have occurred (i.e. parameters have been altered). The one thing that seems regular is that true/false

Hello forum, I put this indicator together to allow me to mark some local times on my charts that I have interest in. Seems to work fine except for the labelling.
