Quote from Blotto:
I've never properly traded more than 80 contracts, so I have absolutely no idea how I would react. I've not got myself truly comfortable above 40. This is more to do with my risk management. I think if I had three million in a trading account, I'd have no problem with 200 lots. Of course this is still far too much risk.
I did my first 100 lot within my first 18 months of live trading. I don't remember anything about the trade itself. I just had an aggressive position sizing plan and one day it was time. Of course by the time I hit 140 (about a month after my first 100) I managed to lose 30% of my net worth in a few weeks. Given that I had started with a 2 lot, I took this in my stride, but have never been near 100 lots since. I suspect I won't for years either.
Interestingly, I took so much risk during the "experimental" phase before I made this my only career and income that I'm not really bothered by size. I know that I have the capability to execute at least 140 lots. Even if I choke at 141, I know I'll do okay with the 140. Equally, even trading an extra 10 or 20 contracts when equity / profit allows doesn't really affect me. I think I'm immunised against the effects as I had one of the swiftest up and down again possible when I first got into trading. I learned a lot of lessons, although I did make mistakes that set me back years. Valuable experiences. I don't hold overnights and I always have stops pretty close. Unless I become good enough to play in the big leagues, I don't think I'll be taking very large hits (or very large gains) in proportion to my capital ever again.
I just look at size now in terms of position sizing and market liquidity. I'm not going to start paying myself more when I trade more contracts - it just means that the account grows a little quicker and I'm another step towards lowering the leverage.
