This is the last version of my KAMA indicator (public at tradingview) with default settings tuned for BTCUSD weekly chart.
In the previous two occasions the first deviation line held well the drop, notice how in the recent November bottom the price was at an intermediate level between the Kama and the first negative line, an high bottom interpretable as a strong signal followed by a strong top (~19600$)
At the moment the bottom is around 11k usd, done again at an intermediate level while the 7500$-9000$ support area is defined by the 1st and 2nd deviation line.
This support area should work especially if the market goes sideways, it could be a nice zone where to buy with reduced risk of high initial drawdown.
There are no guarantees that the market will stay sideways enough to test that support area but strategically isn’t a bad move to buy inside it with a stoploss below 7000$.
