1) using Matched Pattern from 2000 stocks in last 5 years, matched the pattern of SPX over last 3 days, found similar patterns.
2) Use all matched patterns and perform Markov Chain Monte Carlo simulation, burning-in of first 1000 simulation to reduce predict errors.
3) APPLIED different weight, most recent data with higher weight and perform Bayesian adjustment.
4) Perform Bootstrap simulation to get p values and prediction confidences.
For 2), what distribution do you use for the markov chain MC simulation? Does the used distribution depend on the matched patterns you found in step 1?
I used daily to predict short term; Use weekly to predict mid-term.
It works for short-term, mid-term (Like I predicted oil = 40-43, GLD = 109 before using weekly pattern). Sometimes it works better, sometime it works worse, like today, 7+ points off upper bound, and Monday, 12 points off lower bound.
I did not tried long-term yet, since maximum holding time for me are half year, never more than 1 year, so I do not need long-term.
I think I provided enough information, others you need to figure out by yourself.作者: oldhorse 时间: 2015-4-8 16:41
