I’m wondering if using 1NQ to capture a 50pt movement is more favorable than using 10NQ to capture a 5pt movement vice versa. Or something in between 5NQ 10Pt. Is there a mathematical/quantitative explanation? Thanks
What you're really asking is if scalping is better than intraday swing trading. The answer may not be easy, but let's give it a go.
Assuming there's enough liquidity to move 10 NQ, nobody can argue that it's easier to capture 5 points than 50 points.
The mathematical and practical question is how much you're going to risk doing so...?
5 points is nothing, so one have to assume that your stop will be larger than 5 points. Let's say it's 10 or 15 points.
What this effectively means is that you need a very, very high win rate in order to get ahead, because you may have 8 winners in a row (40 points gross) and then 4 losses next at 15 points each. Then you're down 40 - 60 = - 20 points.
On the other hand, if you intraday swing trade risking 25 points in order to gain 50 points, you'll get ahead at the end of the day with a win rate around 50%.
The reason most people fail at trading is because they let their losers run (hoping they'll get back) and cut their winners short. The mathematical result is a negative expectancy.
Bottom line: If can take 5 points consistently with a very high win rate and while keeping risk moderate, maybe it's worth a shot. You really need to maintain that high winrate, though.
