Configuring the indicator:
-DCA Starting Price: the price you want to begin DCA'ing
-DCA Base Amount: the $ amount you will DCA when price is half of your starting price
-DCA Max Amount: the maximum amount you want to DCA regardless of how low price gets
The DCA scaling works exactly like the formula used to calculated the gain needed to recover from a given % loss. In this case it's calculated from the DCA Starting Price. The idea is to increase the DCA amount linearly with the increased upside potential.
DCA Starting Price = Market price to begin DCA'ing
DCA Plateau Price = Market price where DCA amount stops increasing (i.e. when the DCA amount "plateaus")
DCA Min Amount/b] = The DCA amount when price initially crosses below the starting price
DCA Max Amount/b] = The DCA amount when price reaches or drops below the plateau price. The DCA amount will not increase beyond this value regardless of how far market price goes below the plateau price.
