You likely don't need official audit until things get critical. Until then, just keep "audit-able" records.
You are most likely correct. A couple hundred dollars doesn't go far these days. The OP wasn't very detailed in his inquiry, I didn't see the need to be that detailed in the response. We have no idea how complex his trading is. Thousand's of equity trades as a Day trader, just swinging a few ETF's or trading one instrument i.e. ES/NQ. The purpose of the Audit, who requested it and if they stated what was required for certification etc. I wasn't attempting to be accurate on cost, just point him towards his CPA to perform the audit or recommend someone. That is the logical first step.
it is unclear who is the audience of the op. maybe he doesn't need an audited statement ever as implied by scat.. the people who might be interested in him will either reject his strategy prima facie or think it looks interesting. they might let their own accountants review his statements for accuracy/fraud and then make a decision. if the other side is very interested they will use their own accountants to verify your record.
guys, thank you for the responses. I was away from computer and just now got back to replying. I think I have the info I need. Thanks
