Look at this great decision tables technique: http://drools.org/Decision+Tables With decision tables one can specify conditions for firing alarms like "after a drop of 1% of the MA(10)" I think that classic procedural scripting languages are of little use here. I don't see useful algorithms that has to be programmed in extension to the BlogTrader core. The most needed algorithm is a simple loop thru the collection of stocks applying checks and firing alarm signals, though the checks are best expressed in a declarative manner, as rules. Of course, you can do the same thing with JavaScript, but that would be less user-friendly and more error-prone. What about a declarative rule-based approach?

As far as I know all of those that you mentioned are BSF compliant. But then you would still have to choose an 'official' one to implement the built-in macros in.

For example, if I want my sell signal to happen "after a drop of 1% of the MA(10)". How hard/easy would it be to code that? On top of that you may want the sell signal to happen if several conditions ocurre. The most important aspect is the API usability.

What is most important is speed of development -- whatever interface allows you to write the cleanest indicator wins in my mind. Who cares about speed?
