I have the old versions when they were standalone and they aren't really entry signals. After watching his periodic videos back then and trying them out, I've come to believe they're no better than any other indicators. For example the better pro-am shows signs of more volume where it bases "pro" as bigger size orders depicted as circle dots next to the candlestick, but you can kind of tell the same rough ambiguous thing from a dom ladder, footprint or price action. And who knows what the size really means, whether it's more orders betting on continuing a trend or reversal. In the end I don't believe the author has a trading plan or system with the indicators and probably doesn't really trade.
