I can't say that I've seen that, but he is a smart cookie with gobs of experience and a clear understanding of this business from both sides of the table. If he is talking about this stuff then it's a good idea to listen.
As to resources, the best resource I can point you to is Excel.
Make up spread sheets and plug numbers in. My approach is to use theoretical 100 trade samples. I then plug this into actual samples and compare. Having strong performance analytics is the ONLY way of knowing how you are doing.
We use different scaling systems for different market conditions and can move smoothly from one to another as conditions change. For example where markets are compressed, lethargic and participation is below normal levels, we might use small stops, small targets1/2, and take a 5 lot weighted 3:1:1 that way we get risk on our side very quickly and if it clearly won't go we can scratch the rest for a small profit.
On the other hand if participation is high, and we have excellent context, we might move that around with, lets say for illustration that same 5 lots goes out on 2:1:2 and the targets would be on a longer range model rather than the tight ones used in the first scenario.
With 3 lots in a slow range it might come out at 2:1 with not much expectaion of more than a scratch on the third lot and if something more develops then it can be added to if required.
Scaling and implications to risk management is a huge subject and one that professional traders address early in their careers, but most private traders don't ever get their heads around...
