I'll give you that the more experience you have, you "should" make better decisions.
Percentage wise trading multiple contracts is no more profitable than trading one contract.
Where it gets tricky and emotions come into play is when you start looking at the dollar value of your trade.
The reason I said that assumed this was in theory is that I'm assuming you are not a successful trader yet.
I didn't mention experience.
I was more referring to effort,research and due diligence.
The effort,research and due diligence I refer to,serve to offset the emotional aspect.
You have no way of gauging my success so I recognise your statement for what it is-a thinly veiled attempt to garner information.
I don't mind sharing with you that,although I am a net positive trader and investor,I have never been able to make the transition to full time trading from a regular income job.
Again,I am surprised at our interaction on this occasion.You are either being intentionally obtuse or I have overestimated you from your previous offerings.
