There are potential obstacles to your progress which although not insurmountable, will present you with serious challenges aka potential show-stoppers. An awareness of their likely development provides you with at least a basic defense in that you can prepare or at the very least, be prepared, for them.
Even with risk controlled, position size managed within parameters and a continuance of whatever current levels of performance you’re using to extrapolate your future capital base, you will at some point hit multiple consecutive losers and these will be, fairly obviously, when your account is at its fattest. While completely within the criteria of your portfolio management metrics, and however statistically expected this run of losers will be, it will be a body blow from which you will find it tough to recover.
The switch from an intellectually interesting and financially net positive hobby to full-time career upon which the entire edifice of your life (and others?) depends weaves a whole new dynamic into the enterprise and its operation. You can choose at the moment whether to spend 2 hours and 40 minutes each day trading, it makes no difference as your day job pays the bills. With the element of choice removed to be replaced by absolute necessity it will place pressures upon you which should not be underestimated.
When and if you do hit these walls you will find your own way through, but as a general guidance I’d suggest two things: Be extremely prejudiced toward acceptance of the lumpy nature of out of series runs of consecutive losers. Randomness is lumpy and that is your cue. When you get an uncharacteristic run of losers (whatever that is for you) don’t keep stepping up to the plate using your normal risk and position criteria. The market has given you a hint, take it and drop down, stay small, don’t let it get those body shots in on you. The other suggestion I have is to start your full-time trading career when you have a trading capital base which is X10 your currently calculated level. The benefits of this are you will have traded your way up to size that will be necessary for you to maintain an equilibrium which will inure you against the occasional losing streaks without causing you the mental anguish associated with having to deal with financial matters outside of your trading endeavors. When you drop down in size from this base, it will still be for meaningful stakes, but there will that much less emotion tied up in their performance. It will have gifted you that much more experience, which is valuable in its own right. You need to have a calm and quiet mindset to trade day after day and if you’re starting off with the bare limits of what you consider adequate along with the pressure of needing bring home the bacon even if not quite hand to mouth, you’ll be far from calm and the smallest molehill will look, and feel, like a mountain.
These pieces of advice, if accepted, will undoubtedly increase the amount of time it will take you to get to your target full-time trading capital base.
