Consistency of execution.
After you have developed a quantified system with an edge you must execute it with consistency in signals and position sizing. You don’t want to see inconsistency in entries and exits. Not taking your entry and missing a big win can be devastating to your profitability more so than ending up with a small loss. Also, not consistently taking your stop loss when triggered can lead to huge losses of capital that set you back in your equity curve and mental state. Irregular position sizing can also lead to wins smaller than they should be and losses far bigger than they should be, whatever your position sizing framework is it needs to be followed consistently. No trading system will work without consistency of execution.
