I wasted a year of trying to add prem to my style of trading, I gave up, I lost being smart long ago so someone else loves it and can use it a possibility. The only tidbit I ever saw was possible divergences, I thought I saw instances where more or lack of volume gave a clue, but not enough to want to force anything. The traders who have studied the tick well are good at turning points, but that is another indicator where you have to watch it long long time to use it, it is like watching the Dome, just couple instances where you can use bid/ask volumes to your advantage, often times you can't even explain it to yourself, LOL I often think of looking for when price is doing something it not supposed to do, like going to a trend line, will it hold or go through, so watching something other than price can give small hints, but very hard to backtest.
