difference EMA and PRICE in %

[janio973]

Hello ,any ideas on how to create this histogram indicator? thanks for any help

Calculation
The formula for this indicator is quite simple:
Copy(close - MA)/MA
The MA value is subtracted from the close in order to determine the difference between the two values. The difference is divided by the MA value in order to convert the raw value to a percentage.
Note: Our formula above is not specific about the type of moving average. This indicator can be charted with either a simple or exponential moving average (SMA or EMA).

Hello janio973,

If you are new to indicator development I would suggest looking at some of the simple indicators like the EMA or SMA or Bollinger, those show some of the basic plotting and math concepts. The equation you want would be written as:

double sma = SMA(12)[0];
double result =(Close[0] - sma) / sma;

Hello janio973,

That would go in OnBarUpdate. That is just the calculation, you would still have to display it by using a Plot or Drawing Object.
