1. Need a very simple AFL ( for amibroker ) coding within an existing AFL that will access an external xls / txt file(or afl) and return with a TRUE / FALSE signal for original code to process. External file to contain Ticker and allowable Dates.
2. It will add a condition that so many history bars should have elapsed before AFL picks up the Ticker for consideration
This is like a less than 30 min job for somebody who knows AFL coding.
