Amibroker and its applications?

Hi,

I have been trading equities for a while now but it is purely on instinct and common sense. I want to trade professionally, I saw an ad from marketcalls.in about a 2 days workshop on AMIBROKER.

I wanted to know,

1) is amibroker a useful tool for trading?

2) is a 2 day workshop enough to get you started on Amibroker?

3) can Amibroker be used by someone who is not into coding and doesnt know any coding?

4) Should I learn Techical analysis before learning amibroker?

Thanks,
Harshit Patel
