Don't be hypnotized by the win rate.

50% of winnings does not mean that the market is obliged to carefully alternate plus, minus, plus, minus for you. This means only one thing: in a large sample, the result will tend to this value. On the big one, and not on your measly 10-20 transactions.

This is why you need to test ahead of time on a large sample, understand what variance and distribution this win rate can produce, and based on that understanding, prepare to position sizing and data collection.‌‌
