I don't think that you would want an individual forecast rule reach such an extreme value as -43.51 (your EWMAC64). I think that it would be beneficial to clip that.@globalarbtrader :
Do you clip forecasts before weighting them? Currently, my vstoxx forecasts are:
'ewmac8': -0.50
'ewmac16': -9.45
'ewmac32': -23.78
'ewmac64': -43.51
'carry': -12.88
I weight them, and then clip them, which gives me a solid -20 overall. Doing it this way improved performance on backtests iirc, but I'm now 60 contracts short here (450k, 25% vol), so not sure whether I should be OK with that or not.

I don't give a toss whether it improves the backtest, and the improvement is unlikely to be statistically significant.

I agree that NQ and ES have a strong correlation. However, the value volatility of the ES contract is lower than the NQ contract. So for a given amount of risk capital could you have more contracts ES than NQ. For a small account is therefore ES better than NQ, in my opinion. This criteria might not be applicable to you.@HobbyTrading
ES: It was so tightly correlated with NASDAQ that I figured it was reducing diversification to have both. I tried to get as 'distant' equity indices as possible, so went with NASDAQ, SMI, HSI and Eurostoxx. Thoughts welcome though
does the current pysystem run with IB or did you write your own integration? Are your positions live or demo?
