Where can i get a free forex mq4 / mt4 buy/sell signal indicators for download?

I use an EA called "Forex Autopilot". If you want an indicator script, then I suggest you use this one as it's made me a pretty penny for the 3 months I've been using it.You can see a full review made up of real customer comments here:http://www.fxsystemscompared.com/rev_forex_autopilot.html

Lexy, It really depends on what indicator you are looking for. There are literally thousands. However, the best place to look is on any of the free Forex forums online. The best (most trafficked) are www.forexfactory.com and www.tsd-forex.com. Start there and good luck!

what kind of indicators you are looking for? are you looking for a
signal service (renting) or just for freebie indicators and systems??

if a) then try forexautomoney.com (and many more..)
if b) then try forexfactory.com, forex-tsd.com and many more (if you know how to google)

understanding how the forex market works is the best solution (but takes time and hard work)
