[USER=2975]@ducati916[/USER], I'm with [USER=17857]@qldfrog[/USER] - What a great post about maximising profits, linked to the timing of the exit. Yes, it's a fine line exiting a position too early compared to exiting a position too late.


Conundrum

The timing of the exit can be very confusing & difficult to solve & overcome. As coders, we are tasked to navigate between the two. I also like the distinction you draw between "potential profits" & "paper profits" exiting early versus exiting late, the wording used was not lost on me.


Grail

As you have used the word "grail" it's only fitting I make an additional reference to Nick Radge's book "Unholy Grails" just for [USER=50018]@Newt[/USER] - quoting a passage from his book.


To add to Duc's post

Returns alone cannot be a benchmark of robustness of any system. CAR/MaxDD is as good as any metric to measure the "Risk adjusted returns"


For completeness

Duc's an (a) 

I'm more of a (a) + (b) guy - so lets call me (c)

(c) Exiting a position quickly after confirmation that the move is over to protect profits or to limit my loses - the metric to measure this is CAR/MaxDD


CAR/MaxDD

In english, the Compound Annual % Return / divided by Max. system % drawdown is a good measure to use in the strategy development phase.


System Drawdown versus Trade Drawdown

When running a backtest some get confused how the strategy handles System Drawdown versus Trade Drawdown as both are important. In a nutshell, system drawdown is calculated on entire portfolio, while trade drawdown is calculated on a particular trade.


Just for Newt 

This an extract from Nick's book - Unholy Grails: A New Road to Wealth confirming we both value the metric "CAR/MaxDD" the risk-adjusted measure of any trading system.
