"In one year, I'll get about 30 trades for one instrument.
- Those 30 trades will produce on average a 100% return with 25% drawdown.
- By cutting size in half, it becomes 50% return, with 12.5% drawdown,
- By cutting size by four, it becomes 25% return with 6.25% drawdown."
Sorry to be so blunt, but you can probably just stop right there and continue your regular job. Anybody who talks this way, ie literally zero live trading experience but claims he can make XX% profit per year has very little future in this biz. Especially someone who uttered the statement, 100% return with 25% drawdown. This is silly on so many levels I can't even get into it...
If you are hell bent on giving this a try, then get trading already ! Nobody cares about paper traded back tests. Until you have a 2 year audited track record, you have nothing at all. As negative as this was, I do wish you the best of luck if you choose to pursue this.
