Dear Panagiotis

Thanks for your prompt reply.

As you see in the photo which your shared, the H4 EMAs current value did not draw, in the H4 candle which is not closed yet, we have EMA value at the current situation, I want the indicator draw the line till now. It is obvious that the value of the EMA could be changed in every tick.

Please advise

Hello, you can use SimpleMovingAverage rather than ExponentialMovingAverage in the code.
