Yes, I see the point you are making and the truthful answer is yes, you can make consistent profits our of buying calls in a bull market for example but that is dependent on the practitioner having the expertise to be able to avoid all the ambushes.
This is dependent on the practitioner additionally having not only the dealing skills and deep understanding and knowledge but additionally a multitude of finely honed edges that 99.9 % do not have. Therefore the 1 in 3 and the 3out of 4 statistical ratios do not work so efficiently in favour of their buyer however deep the understanding, knowledge and dealing skills might be.
It is patently obvious that the 1 in 3 and 3 out of 4 statistical ratios work out in favour of the writer. This already, without the additional knowledge, understanding and dealing skills is an advantage. It therefore renders all the theoretical knowledge about the greeks and other features secondary.
Therefore approaching all this from the point of view of buying and the greeks and so on, is easily overturned by skilled, informed, carefully assessed prudent writing, is the point I am making, though there are members here who persist to the contrary despite all the evidence, and will continue to persist, for reasons best known to themselves.
