Are high Sharpe systems worth it?

Last june we delivered a system to a client for forex. It has worked well since then. Today we tested it out on the one hour spy and adjusted the stop loss. The sharpe ratio has been improving and during only the last 12 months is over 20. For the last three years is was over 11.

No realistic system has a sharpe ratio of 20, unless it is market making.

I suggest you start searching for what went wrong. Ignoring bid/ask spread and commission?

Frank has likely got your issue sussed: 1) however, that Amibroker screen doesn's show a sharpe of 20; 2) what is entry and exit buyprice/sellprice/shortprice/coverprice (bid -tick / offer +tick) for execution slippage?; 3) are you assuming exit on same bar when it isn't might not have been possible as you needed the bar close price before decision making(look ahead)? 4) commission?

Not a real system, and its curve fitted.

Go ahead and trade it and see what the REALIZED Sharpe/Sortino is. Probably can't execute as spec'ed with slippage, is over optimized and or curve fit, or some other flaw, like execution bar problem all posted above. It trades so infrequently I doubt commision will be an issue. If you can trade a 100 lot for 3 years you can retire and post your glory.....otherwise start small with 1-2 lots or the emini and see. good luck! with such infrequent trades I suspect curve fit problem agead....

Peter,

We are not likely to trade it for a number of reasons. Mainly the annual return without leverage is not high enough for us.

Dylan, There is notthing curve fitted about our tech. We use geometry.
