Trading edge
A trading edge is the reason your trades make money over a long run of them. It is a small, repeatable advantage, not a way to be right every time.
In depth
An edge is arithmetic. Win rate and the size of winners against losers decide it. Win 40 percent of the time, make 300 on winners and lose 100 on losers. Ten trades then bring in 1,200 against 600. That gap is the edge, and costs come out of it.
An edge belongs to a setup, not to a person. You may have one on a breakout in the first hour. The same shape at lunch may pay nothing. It does not last forever either. A setup can stop paying when conditions change, which is why you keep measuring it.
Why it matters
Without an edge you are paying fees to flip a coin. Traders drop a good setup after four losers and keep a bad one for months. Neither was ever measured. Your own numbers tell you which drawdown is normal and which one is a warning.
TraderLog turns your fills into the numbers behind an edge. Win rate, average winner and loser, profit factor, expectancy. Results split by symbol, by hold time and by tag. You see which setup pays and which one only feels good.
