Can a System be reverse engineered just from viewing daily trades/account statements?

Quote from damir00:



assuming the trades are timestamped, absolutely. they may not come up with exactly the setup you're using, but it won't be very hard at all to come up with a system that duplicates better than 95% of what you're doing.

if you let people see the trades, and you are systematic, there's nothing you can do to stop it.

So if the trades are timestamped,what can you do to prevent this, if any?

How do you prevent them from “seeing your trades”?

I’m also curious, how would you go about reverse engineering a system with trades and time stamps?

Finally, assuming you DID NOT have timestamps, just a daily statement, could you reverse engineer the system?

So what can you do to ensure an ultra-technical pro fails in a reverse engineering attempt.

not much. the multiple accounts/multiple techniques can buy you time, but in the end anything one person can do, another can undo.

i wouldn't be worried about it, though, it is pretty unlikely someone with that kind of motivation and capability will be interested in what you're doing.

you can't. if nobody can see your trades, you won't have any trades. :)

i believe another poster detailed this: basically, line up the trades on a chart/charts and turn your computers loose. this is the kind of stuff they were built to do and that quant teams live for.

they have to justify all those supercomputers, after all. :)

eventually there will be a large enough set of trades that could only have occured at one time during the day from which to make the analysis.

this really isn't something your broker is likely to do. if he/she were that smart, they'd be doing something other than hawking stock. from that perspective i wouldn't worry about it.

if it's a situation where somebody may "verify" your track record but they already do trading on their own...then it comes down to trust that they won't, mostly.
 
"my background is ultra-technical and i've done my share of reverse-engineering extremely complex systems. what you describe might slow down the average retail schmoe but it wouldn't slow down a pro for more than 15 seconds. "


oh.
 
...isn't it more likely that if your broker finds you making obscene amounts of money that he will have his prop trading arm solicit you as a trader?

What? Who? IB???
 
...the merest speculation on my part. So far it seems that they are only using my trades as a contrary indicator, as the market always reverses at my entry or consolidates until doomsday around it. I am convinced that they aggregate the calls of lousy traders like me and use us an an indicator. Gotta run. The orderly is unlocking the door to give me my meds.

LOL! :D

Perhaps only my trades record would be more than enough for them, and therefore they don't need yours anymore (sorry to say that!). :D
 
Quote from CPTrader:

ETs,

Do you think that a System can be reverse engineered just from viewing daily trades/account statements?

For example, if you are a systematic trader and run for instance a manged account for a very market-savvy client, do you think they can review your historical trades and reverse engineer your system?

Could your broker also do this?

If so what steps can/should be taken to AVOID/ELIMINATE the possibility of a client (via a managed account) or even a broker reverse engineering your system?

Thanks!


it can be done by experienced TA analyst . I did it couple of times on request as a challenge . With consent of both parties, of course . With knowledge of system trading and developing it is quite easy . I am not a computer expert at all .
You cannot prevent it when analyst has time stamped trades list availlable.
