Known values for the current bar ?

 
- I call "current bar", the last bar in the chart. I mean the uncompleted bar that the terminal is still drawing it.
- I call "index" i, the parameter used in this function:
iMA(string symbol, int timeframe, int period, int ma_shift, int ma_method, int applied_price, int i).
or those array:
High[i], Open[i], Close[i], Low[i],Time[i].


1. Is 0 (zero) the index of the current bar?

2. For the current bar, is that true?
- Open is known and cannot change. It's the first tick price value got during the current bar.
- High is known but it can change. It's the highest tick price value got during the current bar.
- Low is known and it can change. It's the lowest tick price value got during the current bar.
- Close is known and it can change. It's the last tick price value got during the current bar.

NOTE:
- "during the current bar" means: during the terminal is drawing the current bar.

I use MT4 buil 200
Thanks
