i think it all comes down to the specifics of the system and the cracker. if they both work in the same category - let's say break out on eMinis or turtleTrading - then the decoder has a chance. the returns on the account will make the rboker wish he could do the same. he will try to find people doing that thing, might find them and start digging. it is very unlikely from my perspective to find out the exact system, but it could be that he comes close enough to hurt the performance of the first system. if i was a trader trying to decode i would write a simple version that covers all trades of the system plus many more and then let factor analysis try to figure out which factors were used to reduce my sample to the one i try the replicate. i think it is really a lot of work to do such thing and it must be a huge system to justify the expense. and it is an exclusive job - you could not crack when doing other things. for months. easy way to get around the problem is to mix two systems. makes it from my perspective almost impossible to find a starting point for the cracking party. peace
Depends... Yes, if it's an conventional indicator based Buy/Sell Signal. No, if it's a trading system.
If itâs not some sort of a random system, then I think itâs quite possible. Iâm not sure one would need months to crack a system. Just get as many factors as you can find â like prices, opens, closed, indicators â whatever (let say a thousand). Get trades. Combine them together. Run cross correlation between them. Then get most correlated indicators with your trades (let say 10). Combine them again together. Youâll get about a thousand combinations of those indicators. Again run correlation with your trades. Find most correlated combination. 3 hours. If it's not the system, then should be close
I think that if you method is simple and straightforward, then people are either using it or have already tried it. If the method is somewhat complex, then people will probably not "crack" it. Add to the mix your occasionally inconsistent application of the method to further stump your trackers. Is it possible that you are getting ahead of yourself with your paranoia? Regards, Thunderdog
Majority of the customers loose money, anyone who makes money sticks out like a sore thumb. I can guarantee there is an attempt by someone at the brokerage house to take a closer look. It maynot be the management, but some IT guy working late etc... If you recall reading Mark Cook's interview in the mkt wizards book, he was doing really well trading options, one day he got a call from their compliance dept. who were inquisitive about his trading. Similar story by Marty Schwartz who complained about his broker front running his order. If you're doing size, I believe the only way to get around this headache is to use multiple brokers. I hope one day I have this headache
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.
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.
