I think this is the noch of the discussion 
On long term, people taking few trades are way more profitable than the ones taking hundreds of trades per month. you don’t need so many trades. The basic concept imho, is to trade a small account with the big account mentality. What kills small accounts is the “need” to do a lot and fast 
even more, high time frame signals are more reliable cos they include more informations (it’s a pure statistics concept).
Taking trades with PA is not only about finding pins,insides etc etc, there are even too many of them… you don’t want to trade them all, but just the ones that gives you a lot of confluences (swing levels, mean value, S/R…). 1 trade per week is more than enough, belive me 
identifying momentum with cog, i’m refering to how steep the cog is, the more the better (if it’s within the trend ofc)
Hope this helped (for further info on PA check “Price Action, Candlesticks, and the Story They Tell” topic)
