Why scalping signals rarely survive copy trading

[Amanhasnoname]

A signal service posting a 2-pip scalp has a built-in problem. Between the provider's fill and the follower's fill there is a chain: the provider's order, the copy platform's server, the follower's broker, and the follower's own execution queue. Depending on the setup, that chain can add anything from a couple hundred milliseconds to a few seconds. Exact figures vary a lot, which is the point.

Now do the arithmetic. If price moves 0.4 pips in that window and the follower's broker quotes a spread 0.2 wider than the provider's, the follower starts 0.6 pips behind on a 2-pip target. That is 30 percent of the profit gone before the trade has even begun, and the provider's track record knows nothing about it.

Slower strategies with 15 to 30 pip targets barely notice the same delay. That is why most copy-trading success stories involve swing or intraday styles.

Anyone considering a scalping signal service should measure the delay directly. Follow it on a small account for 50 trades, compare timestamps and prices against the provider's published fills, and size the position only after seeing the actual gap.

Has anyone found a scalping strategy that still works after a copy delay, and what was its typical target size?
