Yes, Big Chart is free, I have had problems finding good charting software for Mac, and this is the best one that I have found so far.

I mainly use a 10 day Hourly Chart with 7 Day EMA, Bollinger Bands, RSI, MACD & Volume +.

I use their 3 Month Daily Chart for detecting the Trends, with a 9 Day EMA, and using MACD to indicate an early exit. RSI needs to be between 50 & 80.

RSI 80 generally means overbought, and starting to cross below 50 is sign to exit for me.

I have only fairly recently added the 10 Day Chart, and this has been really helpful in giving good early & exit points.
