Why does extracted indicator data on the chart delays reading on larger timeframes eg 1 hr or 4hr TF?
This is most likely an issue caused by the way your indicator handles data or calculations (coding). Without reviewing the code, we cannot pinpoint the exact issue; it would only be speculation. Please attach the source code of your indicator and, if possible, a screenshot describing the issue so we can better understand and analyze the situation. Once you share it, we will be happy to help!

Hello Vinicius,
Below is the sample code of the indicator am facing the issue with. So I extract the data from macor indicator to create the signal line, on 1 min TF both the value and signal line with exactly as the macor indicator, but on larger timeframes like 4hrs, the signal line data reads different in decimals.
Below is a sample code of how I extract the value from the indicator.

Hi Mark Anthony, I couldn't reproduce the failure you described... Here the values of M1 and H4 match in the 2 indicators (Macor / MA of Macor):

... I may not have understood your question... 😊Hello Vinicius,
You are on track Sir, Kindly extract the data to the chart, both the macor value and the signal line value.
You will notice the indicator value (displayed directly on the indicator) is slightly different from the extracted data on the chart when on the 4hr timeframe.
You currently have the data displayed on the indicator, but my issue is when I extract it to the price chart, it turns to read slightly sluggish on higher timeframes like 4hr, mean while I extracted directly from the same indicator.
See if the IndicatorSetInteger() function helps with this problem:
//--- set accuracy IndicatorSetInteger(INDICATOR_DIGITS, _Digits);

Hello MT folks,
I have a sample indicator I extracted. On the 1-minute timeframe, the data displayed on the indicator appears the same on the chart as I have extracted.
But immediately, I switch the timeframe to 4 hours, the data displayed on the indicator is mostly slightly different in decimals from the extracted data on the chart.
Why does this happen? I believe it would impact the performance of my EA if it functions in that manner. If there is a way to correct this, kindly assist me, please.
