The whole point about tracking points captured as a % of the daily range is to give an idea of how much of the daily offer you’re able to capture, i.e., skill.
Trader A nets a total of 50 points on a 25 point daily range trading one contract, i.e., 50 points per contract.
Trader B nets a total of 50 points on the same day trading 50 contracts, i.e, 1 point per contract.
Obviously, a big difference.
All correct of course, but the way I'd like to think of it is like this. If my strategy requires holding for big moves, this might be something that I'm not able to accomplish on many days. The market after all only offers what it offers. 30, 40 or 50 point winners are great, but these require great entries, lots of patience, and a volatile market.
A 10 point move on the other hand you can expect practically every single day. Its also more probable to get a 10 point winner vs. a 50 point winner. Trying for 10 points is also large enough that it doesn't leave you so exposed to predatory algos , like if you're only going for 1 or 2 points. (although they can of course move the market much more than 10 points sometimes)
So I do think there is a sweet spot, which I guess is very individual. For me, I'd like to settle on a type of trade that sets up many times in just one hour. A 50 point move might not set up properly during the first hour of the market open, or when you are watching live. A 10 point move though sets up multiple times in just the first hour or 30 mins.
Furthermore, with a 10 point move, there will naturally be a higher win rate than for a 50 point trade. And once again, there is a sweet spot for what each of us finds acceptable. A higher win rate on a smaller R:R might be better overall than a very nice 1:5 trade but on a much lower win rate.
And then putting all this together, I want the type of trade that is easy to leverage up. If I can only put on several 50 point trades in a week, it might be difficult to start adding on contracts. But if I'm used to making 5-10 trades a day with a 50% win rate, scaling up my size might seem easier since the trade is over soon, regardless of the outcome, and if I'm not married to any one trade, its easier to just focus on your system, which should make it easier to add on size as the account grows. If you're targeting a much larger win, detachment from the trade might get more difficult.
