Amibroker (AFL)

This is a buy & Hold indicator. I have coded Mr. Appels indicator as per his book. However, I have added BUY and Sell conditions as a point of reference only. Personally, I would use it as a exploration to identify possible long positions. Mr. Appel advice is, “There is only one buy rule and only one sell rule: You buy when the Triple Momentum Level, the sum of the 5-, 15-, and 25-day rates of change, crosses from below to above 4%. You sell when the Triple Momentum Level, the sum of the 5-, 15-, and 25-day rates of change, crosses from above to below 4%.”
