Good entries are everything - 90-95% of effort and research should go towards identifying good entries and how to trade them tactically, in the early stages of the trade.
Exits are entirely downstream from the entry. Having a strategy to let winners run is essential to maximizing your profit factor, but consistently good entries can be made into a profitable system using any remotely coherent exit strategy or combination thereof. Conversely, no exit strategy can turn a losing system into a winning one. My system would be profitable using random exits, so long as my existing risk management was retained in all other respects; I’d be insane to try taking random directional entries across the thousands of available symbols.
It’s true that as time goes on and one’s approach gets more refined, the biggest incremental gains are to be had from improving the exits and thereby capturing a larger total integral of the available MFE, especially from very rare tail events. But that assumes the MFE is there to begin with.
