MEME is a technique to save your trade when the price goes against you temporarily.
Look at this example:

I went in at completely the wrong moment with a BUY. The market then decided it was time for a retrace (temporarily going against me). However the main trend remained intact. Now instead of having your order run into a stoploss, we actually add another trade (because we believe the original trend is still intact).
In the example you can see that the EA eventually had to add 3 additional orders. The effect of this is that my very first order doesn't have to make profit. As long as the average of the whole lot is positive I can still come out with a profit.
Please read post #106 en #107 for some more explanation.
