Nine years ago I would have disagreed, year later-I saw the light but for me was for long term trading. Now, with hedging, have same back tests outcomes regardless of perfect entry or horrible entry providing I hedge correctly.
Many see risk management as protective stops, that is very small part. It is looking at a chart and seeing reasons of not taking otherwise good signal, and based on back testing to develop probabilities of recurring patterns. I could just throw away systems for entry being I hedge, just randomly pick a price, but there is what I call "rental", by staying in the market one takes funds from one area to another. Being in a trade where exiting produces nothing is a loss of opportunity of getting into another symbol with much better entry.
Risk management is also anticipating based on patterns of what might be coming to a retracement or an end and either hedge open profits or terminate trade.
To a lesser degree intraday trading-you don't adhere to 2% rule, you can't continue, or bypassing signals based on recent past or longer term trendlines, but we know people trading their last quarter "hoping" for a miracle. And the miracle comes and they have no account, back to whiteboard and many beers.
