1. What's the difference between End of Turn and Live?
Live will be executed as soon condition is met.
End of the turn will be executed at the end of the current candle
2. Where can I find explanations of "Price Source" Median, Typical and weighted?
"median" is (high+low)/2
"typical" is (high+low+close)/3
"weighted" is (high+low+2*close)/4
3. Next to "Price Source" it says "If bar is used". What are the non-bar options?
If we have Bar as a source.
Selected component will be used.
Otherwise, the entire bar will be used.
For example, U can select "median" or "typical" for MVA (SMA)
"VAMA" will use the entire bar.
4. How can I set the indicator to send a signal immediately when the MA is touched before a bar is closed (or opened)?
Use Live Mode.
5. Since I'm using several instances of your indicator at once, is there anyway to know which chart the alert is coming from?
U can use Label parameter option to add your own text.
