An hour ago, I went out with a friend of mine and it happens to be a drinking hall (bear parlor) where he got drunk and as well trading.
You meant Beer parlor, right?
Are you sure you are alright, mate?
The question is, can you trade while you are already drunk?
I don't think it's something that should be advisable, just like it is not advisable to operate machinery when under the influence of alcohol.
The fact is, once one is drank, the ability to make rational decisions is reduced. Proper decision-making is very vital in trading
