Do you know any free sites for these? I know ZigZag is actually a custom indicator in the MetaTrader4 platform for Forex but I want a free chart site for stocks. I wouldn't mind finding one with monthly candlesticks for the symbol SSO (double leveraged ETF on the S&P 500) and be able to draw trendlines.
Stockcharts.com has both indicators you are asking about. However, you have to join in order to get monthly charts. Their free version has just daily and weekly charts.
