Share Time cycle Finder

We Require a program that will read an Excel/csv file, and automatically find Time Cycles in Shares(stocks). The Excel file will contain the HIgh and Low price for each trading day of the stock. The program will need to cycle through each day, and find possible turn date time cycles. For example, Starting on 4/4/2010 there was a Low, and every 100 Days after that date there has been a High or a Low on that day with a 80% Accuracy Rate. A number of parameters will need to be customizable in the program. For example -Minimum time cycle periods to search for (For example, only search for time cycles greater than 10 days) -Date to start and finish looking for time cycles -How long the High or low needs to hold for it to be a successful turn date (for example, the high price of that day was not exceeded for (X) number of days. -Minimum % accuracy required to display in results. etc The finished program will have the above parameters plus some others, and will be able to select a CSV file, type in the required parameters, the program will then search through the CSV file and return all of the results that meet the parameters.
