i use realtimeHUD, so the best you can use in the screen without going to the pop up is aggression frequency, aka the %of times they bet after the flop...i get aggression factor in the pop up (idk why but its the only stat i can get in the pop up but not put on the screen) i dont really know how to read the aggerssion factor though, heres an explanation of AFQ (agression frequency) that i found online a while ago and have gone with:

1. A stat used in HUDs that takes a formula involving aggressive actions and dividing it by other factors and is often considered in math circles the best determination of a player's true level of aggression.

Explained

Aggression Frequency is not a very common HUD stat, but one that gives a percentage number to explain just how aggressive an opponent potentially can be in a hand. The equation is:

[Times Raised + Times Bet] / [Times Raised + Times Bet + Times Called + Times Folded]

This number is a percentage, and the higher this number is the more your opponent is betting or raising. The more they bet and raise, the higher the number, and thus the greater the likelihood is that they are bluffing or semi-bluffing at the pot. 1.
