Stop loss protects capital from unexpected events like news, liquidity gaps, or simple misreads. Even with high win rate, one uncontrolled move can wipe out gains. That?s why many traders treat it as non-negotiable. Your idea of splitting entries is valid as a tactic, but it increases exposure if the market keeps moving against you. The important thing is that total risk is defined in advance. Whether you scale in or enter once, you still need a clear point where the trade idea is invalid.
