Find best dates, roi and accuracy for stock data

I am not even sure if excel can handle to do this or not but here it goes.

I have attached a refernece page as example format.

In each tab (if all data needs to be in 1 tab that is fine too) there is data ranging from 1-1-98 to 2-20-13 (or whatever i have downloaded) for a specific stock. On a summary page i have information that i would like to meet, ie start date, end date, roi, accuracy etc.

So i need to figure out based on the data i have and the information i am seeking what of the stocks listed would be the best to buy.

so example in the spreadsheet example i have it from 3/1/13 to 3/31/13. So i want to know of the stock data in teh other tab when is the best date to open a position between 3/1/13 and 3/13/13, hold it for at least 5 days and returns an roi of at least 5% with an accuracy of 75% (meaning of the past 8 years on the days it has picked up the min 5% roi it has gone up/down at least 75% of the time)

Any help would be appreciated. I have it built already with standarized days (3,5,7,14,21,28,32 days) and only 1 stock but i want to be able to run the analysis on multiple stocks and it return the ones on the summary page.

Also must do analysis based on adj close column. I also understand that the market isn't open every day, for that on sat and sun i would make it the same price as it was on the last day it was open.

Any help or input would be appreciated.

Thank you in advance
