MT4 does have tick charts and I've played around with it but never really got into it. It only runs on Windows and it's a serious resource hog so I kinda gave up on it for now. Over the past several months I've invested a lot of time into ThinkorSwim which does have tick charts. Time-based forex charts are extremely ugly and MACD, especially in the short term, doesn't represent risk as you'd expect. However, when you switch over to tick charts all of a sudden forex looks "sane" again. MACD, tick charts and forex are a perfect threesome. :-)
