  1. Why did you post your MT4 question in the MT5 General section instead of the MQL4 section, (bottom of the Root page)?

    Next time, post in the correct place. The moderators will likely move this thread there soon.

  2. You created a line from the current candle to the earliest one using the same price; the definition of horizontal.
  3. Also remember, you can't get an n period moving average until you have n candles.
