As a dollar cost averaging method, you could just buy every time the standard stochastics cross up from below 50. That would ensure you catch most of the decent dips with hardly any work at all, and should achieve a much better ave price than buying once a week/month. Do this as long as the SP is above the 200EMA, and pause whenever the SP drops below.
Green arrows indicate where you'd be buying.
I see, so you buy on the downward trend to help save on stock costs. Then when it moves closer to the average and peaks it is worth more. Giving a greater profit % (if you sell at those times).
To understand that better I come back to needing to know how to read and set charts to suit.
