I dont know what MA you are using but it appears yo uhave ALOT of whipsaws here. Try making the purple MA longer so that the aqua one touches the purple one when there is a continuation of the trend. For example you need to decide whether you plan to trade as frequently as this system encourage you to do or are you going to want to trade the trend from 8-21 to 8-25 with the lows of each day acting as BUY opportunites or trade the trend from 8-21 to 8-31 with periodic BUY opportunity like on 8-26. Once you know what kind of trader you want to be (meaning catch every swing or intermediate swings or longer term swings) then you can focus on particular time frame and modify your MA to suit your needs. Realize that NO MA in particular will make you money. You need to combine this with other factors and know when MA are not valid signals. You also need to know how to identify this time when MA are not valid. Its ok to say MA are only helpful in a trend but not in trading ranges,...but how are you going to identify a trading range while its happening and not in retrospect. You have a lot of work to do before you get there.
My first suggestion is decide what kind of trader you want to be and then tailor your MA around that time frame and just plug in all sorts of numbers and experiment with every combination of EMA, EMA crosses or triple EMA crosses and EMA, SMA crosses and every combo you can think of.
Good Luck
