Need work permit for private stock trading?

Once again. The burden of proof is with you.

And I don't need to prove my opinions. They are opinions.

​It is my opinion that if the authorities decide to run you through the legal system you're done for.

Good that you finally said the key word; 'opinions'. You will find find that in civil discussions, these have to be supported with facts, of which you brought none so far.

here is a fact, if an immigration official or DOL official gets in his head your are working, irrespective of what you are doing, you can be charged with working illegally, its then up to a judge to decide whether the charge is warranted or not, which while the case is being processed can cause someone significant grief

and the above is the only fact which is important in the Thai context

Sometimes I scratch my balls. Do I need a work permit? Is there a policeman or a labour department official or an immigration official hiding under my bed documenting this scratching as evidence of illegal working? Could the self-appointed adjudicators of TV please provide a definitive ruling on this and advise my next move. I lie awake at night worrying about this.

Thailand does not need people like you. You absolutely on breach of the labour laws and taking the work that any Thai could do. I suggest you employ a Thai national as your ball scratcher immediately. 555555

I see this topic has arrived at the point where it must be closed. The OP has got his answers, in fact many answers, and a lot of off-topic information.
