Added Trending Oscillator and MACD Oscillator in a script.
Trending Oscillator: big trend to follow (gray background).
MACD Oscillator: use this one to determine entry / exit point.
The default over bought and over sought rates are 100 or -100.
One safe long strategy is to buy the first or second pullback: when Trending Oscillator turned green (over 0) and MACD is red (below 0).
You can use in combination with other tool to find the entry/exit points.
