I have infrequent access to the DeMark TDRS service on Bloomberg. The scanning capabilities are second rate when compared to AmiBroker.
The Sequential AFL codes in this thread have a close accuracy versus the Bloomberg. . . and I have found that the "Explore" function does a good job of listing Setups and TD13's across a broad list of securities. I only wish there was an AFL that identified Combos.
I have attached charts of NIFTY and APTY from Bloomberg (TD13 in upper pane, Combo in lower pane). If anyone is programming Combo I would be available to compare future official readings with an AFL.
