Amibroker and MultiCharts are fierce competitors; if you post your questions here, you will be sure to get fast response from both companies. ;-)
HA.....We'll see. So far though, only been screwing with AmiBroker for about 10 minutes thus far(downloaded it earlier today), and I can't even figure out how to manipulate the studies yet(reading the manual now). In all the posts I've read in the archive, it seems like people really like amibroker. Results of multicharts were generally favorable, but amibroker seems to have a larger percentage of more favorable reviews, in both the regular posts AND the 'reviews' section. Honestly, so far I think I am liking Trade Navigator better than both of them(for ease of use), it's just waaaay too expensive for what I want to do though. The version I have doesn't have nearly the functionality I want. Damn software complications......
