On Balance Volume EMA Trend

I have just taken the On Balance Volume and added an EMA with a little color to visualize the current trend.

版本注释:

I have added alert conditions for when the OBV crosses above and below the EMA. I have also added the option to use realtime data for these alert conditions. If you wish to use only confirmed data then you need to uncheck this option and the alert will only be able to trigger when the current candle closes.
