Create a separate window volatility scanner. Indicator show volatility by candles. I like to use High-Low, Open-Close data to calculate Volatility. User can input 20 symbols to show volatility. That is multisymbol mode. With multisymbol mode indicator show latest 5 candle volatility. When multisymbol mode "false", Indicator show chart symbol historical volatility data. And every important movement notify by mail, popup and push alerts.
Please kindly do not apply if you can't develop Multicurrency, Multitimeframe, Buttons and Graphics.
