Bet size is not often mentioned here on ET. But it is very important. The aim of every trader should be to increase his bet size as his account grows. If you can get to a decent trading size then you can start really making large sums of money. I am currently betting (or risking) £3000 GBP per trade (about $4000) using an automated day trading strategy. This bet size represents the risk to my stop loss point. e.g. If my system dictates a 50 tick stop on say CL (which has a $10 per lot tick), then I would trade 8 lots, to give me a $4000 bet size. My first target is to get to a £10,000 bet size. The automated software will increase my bet size as my account grows, and decrease after losses. Such that when I double my account from current levels it will be risking £6000 per trade. But if I lose half, it will be risking £1500. I am going to keep track of the bet size changes in this journal. And hopefully this will help me focus more on this aspect of trading rather than being focused on short term PnL.
