I did post this somewhere above, but anyone using really small time frames to trade off, ie, 5,10, or 20 seconds, who is also using MACD, I found that rather than the standard formation of 12/26/9, a 65/100/15 will smooth the ribbon out nicely and even give you trading signals, though as always you will need to have another couple of confirmatory indicators with it. I don't use it on bigger time frames then these, because the standard formation, say on the 1m and above, will work better for diversion.
