Due to the my investment optimization need, I use the Google finance, Yahoo finance API to create some simulation for ETF investment operation and calculate its performance to find the best algorithm in trading;
It is my personal simulation, the current display of investment % is a fixed % model, it will modify each month, the dynamic investmnet % will be my internal reference. The selection of those ETF as a target ETF for the investment % to adjust is coming from several reason, one of most important reason is those ETF will not have a big fall from Jan/26th to Feb/26th, second reason is the ETF set has its combination effect to minimize the investmemt risk, so we add new back up "2009 Feb ETF Set 2" to optimize the trade performance if some ETF cannot trade in 2009 Feb ETF Set 1 due to Dow drop below the support on Jan/30th .
