Averaging is good if you have lots of capital. I don't recommend averaging if you don't have lots of capital. The trick in doing averaging is simple. Compute the high and low of a pair you want to average in a year. In short get the high and low of a pair you want to trade in one year span. In this way you will know if you going to hold your position in a year how much capital you need and in their you can compute also how many times you can open a position without getting MC. In this way you realize how much money you really need to do averaging.
