Hi Ray, It's a software program, Excel spreadsheet based to be more exact, that helps chose prices to enter a trade by looking at recent history and giving you possible ranges for entry so you can get in a bit lower than just guessing.
Hi Ray, It's a software program... Got mine from ebay a few years back... I like it and just used it again today as a entry point indicator. About $20 delivered to your house on CD... Best regards, Ken
