Can I get the value of RSI(14) of 1 minute data in 5 minute and in higher timeframes? I tried this but it didn't work. But, 15 minute RSI is visible in lower timeframes ( i.e 1 minute, 3 Minute , 5 Minute, etc.) but not in higher timeframes ( >15minute ).
PLEASE NOTE that you can only compress data from shorter interval to longer interval. So when working with 1-minute data you can compress to 2, 3, 4, 5, 6, ....N-minute data. But when working with 15 minute data you can not get 1-minute data bars. In a similar way if you have only EOD data you can not access intraday time frames.
