I don't see 100 MA line, I only see 300 and 1000. But you said that you used 100 before, so I think it could be some kind of cache.
That Access violation problem... maybe you ran out of RAM. I have never seen such error before, but I have 32 GB of RAM and most of the time I don't think about it. I also never investigated how EAs are filling the RAM, so I'm not sure from where these 4626 MB are coming from.
MQL5 is very weird sometimes. The thing is, in order for me to fix some problem, I need to somehow replicate that problem here on my PC, so I can do tests and everything else
