Hello everyone
I am using the SAR formula as here below.
My main timeframe is 15minutes, But I am trying to use this SAR indicator in the 1H timeframe.
I have therefore created an basic indicator to view the in the 15m window the values of that 1h SAR
I am using the GRAPHONPRICE function to check the values used for my strategy
However, if i am facing several issue:
– in the 15m timeframe window
– the extreme SAR of the 1H timeframe(Lowest or highest in a trend) is delayed by 1 or 2 periods
– this is the only issue with the indicator – the delay
– but with the stratagy, there is the delay with the extreme point, but then every steps / variation is different from the 1h window
I have of course expanded my 15min chart to 10k, then 50k then 200k units, but no changes;
Please note than I am facing the same Delay issue with the basic SAR (1 period delay)
Please not as well I have teste those configurations with the updateonclose function or not
ANy idea ?
Thank you in advance

Je ne suis pas certain de bien comprendre, mais pourquoi ne pas utiliser directement l’instruction SAR avec le MTF dans un indicateur:
timeframe(1 hour,updateonclose)
isar = SAR[0.02,0.02,0.2]
return isar
Thank you Nicolas
I agree : with the SAR function, this is working.
However, there is a slight difference in terms of value between the SRA function and the SAR formula mentioned here above ; moreoverthe value is totally different when the SAR is touched by the price.
Point is that I Still do not understand why in this case this formula gievs different results as an indicator or a called function under a strategy.
I am still investigating – I am moving forward in the meanwhile with the basic SAR function
