Why increase leverage? Didn't you say to keep it low?

Today's review, failure, the biggest failure is baby, the 0.1 expected support did not hold, tried a position of 40% at over 5 times leverage, entered at 101, from profit to a stop loss trigger at 95, lost 50%, yesterday's profit from baby wasn't enough to cover it, fortunately, in the evening started to earn 80% on wct, 40% on om short, completely recovered baby’s losses and made an extra 10, but unfortunately, there were too many stop losses earlier so could only do 20% position, overall followed the existing method, except for baby, not only increased the position and leverage, but also set the stop loss to 10 points, need to change next time.
