Before you run the exploration there is a time frame setting you can change that to your desired TF
Look for a Spanner Icon on the Analysis window - - - using that access the settings window
On the General Tab >> choose your desired Periodicity for TF
If the AFL uses TimeframeSet//restore//expand//getprice, then in that case for Periodicity choose the smallest one
In ami it works only from lower to higher TFs . . . not other way round
Happy
