Beamstas, I do use fixed fractional position sizing. I just rounded the figures for ease of people reading my post. I also have a few different accounts with different internet brokers therefore my position sizing is based on the capital I have with that broker. I also use a spreadsheet for trade management and I check each morning on available capital for trades and risk parameters. I enter a trade with this knowledge in mind and then I update my spreadsheets. It was just a stupid stupid mathematical error that if I ever repeat again I will force myself to go back to school with my 5 year old son.
