### Comment:
Right. So yeah, position size is it. It's actually mathematically impossible to win long term if you commit too much of portfolio risk to one trade. You just can't. Eventually you'll hit a string of losers and get wiped out. I made an excel calculator to demonstrate this. It doesn't do naked shorts but give it a try and you'll see. Anything above 5-10% is crazy risky. Not just risky, it's a plan to lose. https://twitter.com/JackBeTrader/status/1027750639533797377/photo/1

Your spreadsheet doesn't work in Google Sheets...the  'run' button doesn't show up. Does this only work in Excel?
