According to Chartist based on a similar question: "If your portfolio size is 100K you should have double that liquid and unencumbered which you can lose without seriously affecting your financial future. i.e. 200K in the bank which you can and will probably lose. What is more important is that what you do with any profits you make. They must be removed from your trading account regularly and speedily. I would recommend that you do not increase your portfolio by more than 20% per month (non compound). Your initial success will be your biggest handicap. By increasing your trading capital you create the conditions for trading suicide on a grand scale. Put the profits you make out of reach. As you capital grows the idea is to be reducing your risk exposure with every trade....not the total risk but as a proportion of your capital. What you start with is immaterial ....it can be a little as 50K. Just know that you will probably lose that twice over and that your initial success is no measure of success over the long run"
