It is important to again and again remind yourself of what can in terms of losing streaks, drawdown etc. etc. Below something I built myself for that - I went ahead and adjusted it to your [target] metrics 50% winrate 1,6 profit factor 50$ stoploss per trade see for yourself, if you have any questions on particular fields, feel free to ask! P.S.: the probability of 7 losses in a row is .5^7 which is still ~ 1%, so even if you hadn't deviated from your plan (which I assume is playing a role in your streak as well) you still have a 1% chance of hitting that drawdown. For one event, 1% sounds small - but for an infinite number of events (assuming you don't stop trading suddenly) it becomes inevitable. So know what can happen, decide how much "down" in % of your account you can stand IF it happens and start building your risk from there. In below example, if you might not want to lose more than 30% of your account in any given drawdown, you'd need approx. 3k for trading a 50$ stoploss. Hope this helps... ST

I understand what you say. But I didn't increase my risk because I was loosing money. I increased because I have to increase it every 2 weeks in order to get closer of my goal. Increasing risk is totally independent of the performance and it has to be. When I started the week with the new risk I didn't know I'm gonna take a drawdown. The reason of my failure is I was scary that my system doesn't work anymore and not really the money.

This is an interesting idea.

Increasing your size after loses is exactly opposite of what the Kelly Criterion tells us to do. I think that is a pretty typical mistake because cutting size after loses is not intuitive, feels wrong but it is absolutely correct.

This seem like a odd thing to do.
