there is no problem with professional gambling. the op wanted to know why it is that most option traders lose. my answer is simply stating the obvious, this is what i call professional gambling. some get offended by that, but what does a trader do? place bets. simple as that.
The reason why most option traders lose (if they lose, I do not know) is that they are buying call options which are overpriced enormously on a rising market and fall a sickening amount on a market fall. Attached to the option price is a time value which wastes away to zero as the option nears execution so that, even if the market price rises, the best that the option price will do is stand still ie. the purchaser is disappointed at the little amount that he, finally, made.
In the eighties, the option business was advertised widely by brokers as a means to sucker in new and inexperienced clients with the claim that spreads limited any possible loss. What the client did not realise was that the losses heavily outweighed the gains, due to this time value.
I was an option trader of the eighties. I lost quite a lot of money and when I finally did get the hang of it it was because I bought options a long way away in time and sold them before the time wasted started to kick in. This wastage gets serious within the last few weeks before expiry but they are the ones that my broker was trying to sell me. In the end, because of the large amounts involved, involving thousands of pounds, I reverted to trading normally and have not gone back to options. Probably the business has changed enormously, since then, and others would know more about it. However, I doubt whether betting on options is any safer, except that less money is involved, perhaps.
This a part of the gist of it. Options are a hugely complicated business and I would tell guys that if they are unable to make a decent income from simple trading then forget optiions----frankly, they are up against serious pricing experts.
