I am going to write it here for future memory and reference, and in case someone would like to share similar experiences. I thought I had it all figured out. I had built about 20 different trading systems, that I thought were quite different among each other, all of them triggered trades that lasted a few hours and all of them about 60% of wins. Starting in November, I went from 8000 dollars to 26000 dollars in one month. Then, at the end of November, I took out 8000 dollars to repay the loan from the bank, and had 18000 left. Then I went up and down for two months, but always in the range between 13000 and 18000. Then in the past few weeks, also by adding a few losing discretionary trades, I went from 18000 down to 3000. Now I am being patient, very very careful, but obviously I am pretty much screwed since I have such a low capital. Nothing else, just wanted to share this terrible experience. I thought with so many systems and about 18000 dollars, I would be ok, with no risk of big drawdowns. Instead here I am, with 3000. It all happened in just 2 weeks.
