Hi Fabian,
After you do the 9’s and then go back to the chart and then come back to the 9’s, the 9’s should change to 2147483647. Are you getting this or a much smaller number? If a much smaller number then your broker is limiting the historical data. For example with the FTMO server the data for M1 goes back to September 2023. I would contact your broker to see if they can increase the historical data. If your broker cannot give you more historical data I would consider finding a different broker.
With the historical data I see available on the chart you do not have enough historical data for a smoothing of 50 periods.
Alan,
