Quote from manz66:
MAE/MFE:
'In other words, once you enter a trade, how far against you did it go? If you take a bunch of trades genetared by an entry technique and separate winning trades from losing trades and plot the MAEs for each (let's say 10 days after entry for example), you'll find that the MAEs for each are different. If you plot a scattergram of the MAEs for winning trades using any spreadsheet, you'll get a good idea of just how far winning trades normally go against you and you can use this to figure out where to best place your stops'.
opposite is MFE.
