there’s many way to get your system turn into automated version. first you can start looking for good coder, mql5 site has this kind offering, and off course there’s a fee depend on how your strategy.
there’s also free way to do this code build, go check with ff or t2w forum, there’s a free coder thread. but you need you make sure your system are profitable one, do some manual trading activity based on current strategy, a profitable manual trade are much more easier to code, and many coder would help too, since they’ve got a profitable trading system for free, best of the deal, right ?
