Fast SMA

Fast SMA is based on the simple moving average and adds to it more flexibility.
It is a composite indicator, as it uses sma and counts factor that gives more weight for a more recent price index.

The difference between sma (thin line) and fast sma (bold line) you can see on the chart.
Fast sma with default parameters with this script is faster then ema with the same length.
It has flexibility almost as HMA with the same length has.

After using it for two months I found this ma very interesting and decided to share its code and the way it can be used.

FSMA and price index interact:
1) FSMA acts as support or resistance giving price line good pullbacks.
2) If price breaks through FSMA the stop of this move form strong support or resistance level.
3) if price cross FSMA without cutting move of make fuss on FSMA it forms range. In this case, FSMA break must be considered only after price leaves the range. In such cases, FSMA usually shows the direction by giving additional price pullback confirmations.

On the chart I added some comments and marked SR lvls, zones and strong moves of BTC since 2018 till now with submitted FSMA strategy.

I wish you good trades.
