This has to do with the underlying instrument index and what stocks it follows not the deviation levels. The formulas is the same on all four - pulling the Unique IV for that instrument. Its not a deviation accuracy issue so much as unique parameters to that instrument.
TF is comprised small cap stocks. Its in a class of its own. It often moves much faster, more volatility, and has much lighter volume. It overall normally has lighter volume than YM - look at a monthly chart to get a bit better view of volume
NQ is technology stocks which can be prone to move a bit faster as well
YM and ES are more prone to move in lockstepwith each other. (large cap stocks)
So as you are seeing either A it works better on this indice versus that indice. On the one does not work as well on what alternatives are available how could you change up the strategy on the other indice or use that to your advantage etcā¦ (ie otm versus ITM etcā¦) or possibly due to the increased volatiltiy you need to widen the parameters on the strike
[quote=dca78_00]Darrell - I am wondering why the indices in this test have such different profit potentialsā¦
I understand, just by looking at the charts and the numbers, that the much larger losses in TF are due to the fact that TF more than any other index, reaches the entry strike level and passes through it. TF reached 27 times on C trades, 19 on Cā trades, compared to: YM - 13 on both, NQ 9 C Trades and 16 Cā Trades, and ES had 11 C Trades and 12 Cā Trades reach.
Since, more often than not, the indices move in step with each other, I figured that maybe volume has something to do with it, and crunched the average daily volume for each index. ES had the highest daily volume (for a month) of 1,541,800, NQ was second highest with 229,550, then TF at 106,800 and finally, YM at 98,150.
So, I know there is a link between reaching the entry strike and profitability, but volume has no correlation to the profitability. So, I am assuming there is a part that I am missingā¦and it is bugging me!!! (Canāt help it, I am an engineer by trainingā¦)
Any ideas???

[quote=dca78_00]Mark - I thought so (and think so), but was trying to figure out if there was some seasonality bit that I am missing. Because the dev levels are accurate, but why does this work better for some and not others when the entry is based on dev levels. Like I said, I am an engineer, and even though it works pretty well, I need to know whyā¦
