As you input each price the program determines the relationship that each price has to the other , and then examines every possible combination in real time as you continue to input data. A price will be forecast within 2 or 3 seconds, depending on your machine. You have 3 options. Option 1 is to take the opening price from the previous 5 Monday's, and input same to determine a forecast. Or you can use the previous 5 days opening prices, and determine a forecast, or you can use the Friday's prices, based on the hour peaks to determine a forecast.
Combinations are endless.
Consistency as to time peaks is essential. All stock markets worldwide freely provide the information required. In addition to forecasting a price this program will also indicate a trend if one is evident. If no trend is evident, no box will appear. From the above options you can determine if 2 or more options reveal a similar result.
