I have developed a strategy by trading open price. However, how should I make order in practice to make the return of my strategy as close as in backtest? There are some ways I can think of: 1) Send limit order with limit price in call auction period before market open. This way seems to able to get...

I am developing a factor model to predict price change. Bayesian Logistic Regression seems more advanced than the traditional Logistic Regression. However, as in this matlab example http://cn.mathworks.com/help/stats/examples/bayesian-analysis-for-a-logistic-regression-model.html Each feature vector...

May be that's right, but as I know, factor model is still popular.

<t>I want to calibrate a mulitvariate linear regression model for forecasting asset return. Now I am doing the following procedure. Subjectively picking up observable factors, like interest rate, fx rate, equity index. Download the data from 2007 to 2016. Select a rolling window, with size 1 year, 2...

<t>I am a beginner in robust optimization. I want to get a robust portfolio with a Worst-Case Conditional Value-at-Risk method. This requires a minimization of loss considering various scenarios with parametric uncertainty. Finally this leads to a problem like min_x(max_U(g(x,U))), where x is the po...

<t>Thank you all for your suggestions.Alan, I have tried adding constrains to the mean-variance strategy. If there are n ETF, then each ETF's weight is in the range [0,1/n] if forecasted return is positive, or [-1/n,0] if forecasted return is negative. The after minimization, the weight of each ETF ...

<t>Thank you DavidJN. I have implemented a simulation to test hedging strategies. However, I am not sure everything in the real trading environment can be easily simulated.

I have some question and don?t know how to begin:(1) If my plain vanilla option is deep in the money at its expiration. Then I must hold a large amount of the underlying future. If the option payoff at the future?...

<t>Thank you daveangel.I think that this can be cured by pricing with carrying cost theoretically. However, it seems that there is still an accounting issue. Say, we have sold a call option expiring on Sep and hedging it with June future. Suppose we hedged the option perfectly until May. On someday ...
