After going through the reviews and discussions on this site, it seems to me that both charting packages are excellent. Can the experts here help me decide? I currently use eSignal but it is too primitive. I tried TradeStation 2000i but I found it too buggy. I have used MetaStock EOD in the past, but I heard that the real-time version is not very resource efficient. Good programming language support is necessary. The ability to control fibonacci drawing tools programmatically would be a plus. I do not need fancy backtesting tools. Thanks in advance.
