Tutorial 86 | Calculate exponential moving average using PriceSeriesProvider

In this tutorial I demonstrate how to plot an exponential moving average from a 30 minute price series provider (PriceSeriesProvider) on a 5 minute chart.

The biggest challenge with this sort of calculation is that the EasyLanguage indicator is applied to the lower time frame and hence runs on every 5 minute bar, however we actually only want to perform the exponential moving average calculation at the end of each 30 minute bar. Another issue is that the historical plot behaves differently from the real time plot.

The image shows the tutorial 86 program applied to a 5 minute GBPUSD chart. A 30 minute GBPUSD is plotted as data 2. Exponential moving averages are plotted based on both the price series provider and data 2. In this image I also plot Close of Data2 and PSP.Close[0] from the PriceSeries Provider.

In the video below I demonstrate how to create the historical plot and how this causes a miscalculation for the real time plot. I then demonstrate how this can be corrected.

The program plots the ‘real time’ exponential average a different color from the historically calculated exponential moving average. I have also plotted the same exponential moving average calculated using data 2 set up as 30 minute GBPUSD bars.

To create a price series provider, I drag the PriceSeriesProvider from the tool box onto my program workspace. I do some initial setup using the properties tab. I then copy the code from the ‘designer generated code’ and copy it into the program and make some adjustments.
