Here's the setup that I am currently using. I'm using FXCM to execute my trades. They had one of the lowest spreads that I found, and also had the microlots that I wanted to trade with to start, and if you search around the Internet you can find a link where you can signup and they give you 25 dollars free to start trading with! If anyone is interested I'll find it and post it here.
For charting I use the demo of GTS Pro, FX Accucharts. Here's a pic of how I have them set up for the 15 min/4 hour GBP/USD charts. I was able to get pretty close to how PipSurfer has his setup with Xstick.
I have it set so that it does a screen text alert and a sound alert when the low Moving Ave overtakes the high Moving Ave, and vice versa.
Here's a pic of the setup of my alerts. Again this is setup in AccuCharts from the GTS Pro demo account. I'm sure you could do it also in an MT4 chart program, but I haven't gotten to really fool around in one that much yet.
