@Gle: Do you mind if I ask what sort of things your scripts do?
Don't worry, I am not after your code or your trading secrets
Just trying to get an idea of the scope.
I have only used MT4 (ages ago) on demo versions of "real" trading platforms, and then only for various indicators (those provided plus a few custom ones). Although I used to be a programmer (and enjoyed it), once I had decided that most indicators were not for me, I decided not to waste energy trying to program them, and concentrate on the actual trading and market knowledge. Therefore, I never got into things like automated trade opening or management - since I was never going to trade on the real platform (I only spread bet and want to stay that way), there didn't seem much point in learning it.
Now there is the possibility in spread betting though, the world may have changed. While I will never be a fan of fully automated trading (not for mere mortals anyway - different if you are a quant), I do think there could be a place for automation as an adjunct to intelligent manual trading. I suppose the obvious thing (apart from indicators, if used) would be customised alerts, and customised trailing stops.
Any comments?
