Solid trading platform choice

I can do a proper tech analysis on my traded pairs in the MT4. I worked with other prop trading firms and for some reason all of them tried to implement their own proprietary platform which is surely not that good as MT.

Just the fact that I can upload some custom indicators easily in MT makes it way more usable.

Also the opportunity to apply advisors is a nice one. I have to pick a suitable one that will have a more conservative trading strategy in it.
