Confirmation delay: the price of waiting for one more tick
Posted: Sat Oct 31, 2026 7:05 pm
Waiting for confirmation before entering reduces false signals. It also delays entry, and the price moves in the meantime. The trade-off is central to scalping.
If a signal has a 55 percent chance of success on immediate entry and 62 percent after a two-second confirmation, but the entry price is worse by 0.3 pips on average, the net effect depends on the target size. With a 3 pip target, 0.3 pips is 10 percent of the profit, probably costing more than the improved accuracy gains.
The way to evaluate is testing different confirmation delays, from zero to ten seconds, and measuring expectancy at each. Plot the curve. Often the curve has a hump, an optimal delay, and declines on either side.
The optimum differs by volatility. In fast markets, delays are expensive. In slow markets, confirmation costs little.
Adaptive confirmation, with shorter delays when volatility is high, can capture the benefit of both.
Include realistic entry prices after the delay, using the ask or bid at that time, not the original signal price.
Where does the optimum confirmation delay sit for the strategy, and how does it vary with volatility?
