Commission impact on scalping is disproportionately large relative to the target size and the traders who miss this tend to be consistently surprised by why their win rate does not translate into the profit they expect. On a 5-pip scalp target with a 0.7 pip commission per side the round-trip cost is 1.4 pips which is 28% of the intended gain before the trade has even been placed. Running these numbers through https://roboforex.com/beginners/start/profit-and-loss-calculator/forex/ with your actual commission rate and lot size makes the impact concrete rather than conceptual and often leads to the conclusion that the target needs to be wider or the lot size needs to be smaller to maintain a viable risk-to-reward after costs.
