>>>>Clearly, delaying delaying the Buys using a MACRO Filter is not a form of Cash Burn Rate Reduction but rather it serves to invest the available cash more efficiently at a lower price. <<<<
It also allows you to sell at higher prices.
The advantages are well known but the disadvantages are that if the Trading Range is not very wide a lot of volatility capture could be missed if the Buy and Sell Limits with the MACRO filter are far apart.
I imagine this is true also and why I have not done it.
I have thought of using a 13 day and 30 MA crossover. With something like 50 and 200 day the price has to move too much against you before you trade. So you give up a lot whether buying or selling.
