Bias and key levels / Support and resistance levels/pivot

 

Hi,

Reference to my earlier discussion https://www.mql5.com/en/forum/127673 here is what i want to find out

What exactly are the bias and key levels.

Support and Resistance levels are developed because of price action where the price is bouncing up and down Pivot points can predict future support and resistance levels based on previous day high,low,close values but what exactly is the bias and key levels and how they fit with other 2 above
