The next step is to use diagonal trendlines.

I got them free from here:

Bollinger Bands
(on/off button)

Another way to explain Bollinger Bands is when the candles are hugging the upper green bands,
that's a short-term uptrend.

When the candles are hugging the lower red bands,
that's a short-term downtrend.

The middle line of the Bollinger Bands is just SMA(20).
