What is illustrated above is the following:
"BD" means Break Down point. In other words, Price breaks down from previous support pivot.
"T2R" stands for Tries to Recover. In other words, Price tries to recover the Break Down pivot.
Also highlighted is the "3d" criteria on the 3/10macd.
As a reminder, the slow line crossing below (or above) the zero-line often precedes a 20-50 Moving Average crossover (which in the above 30-minute chart approximates the 1.5- & 5- Day Simple Moving Averages, the Green and Blue moving averages).
Also, the "3d" criteria can define areas of important support (later on being resistance).
Just for illustrative purposes, below is a daily (left) and 30-minute chart for comparing the 5- & 10-SMA on the daily with the 52- & 117- SMA on the 30-minute chart.
