Using Kagi with 200 moving average for DCA

I am testing an idea where an investor can maximize his dollar-cost averaging method by using the Kagi indicator.
A Kagi chart plots prices like a snake, continuously. When the price falls, the line appears red in color. And when the price rises, the Kagi line appears green in color.
It changes color (from red to green and reverse) when the trend changes.

Buy Entries as long as it is on green week
Pause Entries if it is red
Emergency sell if Kagi crosses under the 200 moving average

Todo: convert kagi to a pinescript and backtest the strategy
make sure to include pyramiding to make it realistic for Filipinos to invest weekly
