Can you either personally go into statARB or recommend a good educational source?
Also in regard to your advice - I appreciate your advice in the same way I appreciate all other posters. There's plenty of time for me to go away. I'll consider it at some point.
Just check my (few) contributions on T2W.
Basis is always a sound scenario of possible outcomes, no matter what instrument involved (stock, option, futures, etc).
PLaying the market on the long or short side with LINEAR instruments (stock, futures, rolling spot, etc) asks for better forecast power than the market has. If you have none, like me, leaf it.
Using instruments that incorporate premia (options, but a lot of other products you might not be aware of as eg the USD Index, or the USD Nikkei futures) usually offer opportunities on the short side. BUT here your hedge is essential.
THe only linear game in town I know, is swap free arb. Long USDCHF with "normal" broker and short USDCHF with a swap free broker.
Everthing else needs real knowledge about option pricing. You still have not declared your know how background.
Do not get me wrong,
I did not say you should go away. I just said, if you hope to recover your losses by merely disciplined trading,
your chances are very meagre, if you are not prepared/able to bring new funds to the table.
Especially if you have "some idea" about what you have done wrong. In such a case you should define your "new strategy" as soon as possible, and you should test it. Test it, but not with the usual angst in the real market, but fiercefully and intensive with real historic data.
No idea, whether you have an option database. Buying the data is not cheap. But it allows you to find out soon, wether your hopes have ground.
