How I design a "1 trade"
A single transaction for me is not "just call a direction + casually open a position," but a small model:
Input:
Entry price = Breakthrough / Pullback / Key interval edge
Stop loss price = The position where the structure is broken
Process:
Risk = Distance between entry price and stop loss price × Position size
Target = 2 to 3 times the risk (2R to 3R)
Output:
This trade is +2R / +3R / −1R
As long as I maintain:
Average profit R value > Average loss R value,
Even if the win rate is only 40% to 50%,
This system is statistically profitable.
I no longer ask "Can this trade double my account in one go,"
I only ask "Is this trade reasonable in my system."
