Travi,
I need a help on this one too.
its Supertrend AFL
I modified the below code with ATR period as 7 and the factor as 3 but it looks like producing different result than that of investing.com 's suertrend with 7 and 3 values.
I have provided the chart of banknifty in 5 min chart with supertrend 7 and 3 taken fron investing.com. if you use the below code in amibroker for banknifty, it is producing different result. Could you please help

Note: unfortunately I dont have banknifty chart from amibroker. its bit complicated.actually I am checking this afl with options contracts and Investing.com and my SAS online trading terminal are producing same results for 7 and 3. so I compared my optiones contract from my trading terminal with amibroker chart. they are producing different results

Chart and Debugger in Editor are different.
That is why in my first post I told you to provide as much info as you can. so in this case, you should say i'm checking syntax in Editor.

If you want proof :D goto Tools > Preferences > Debugger

You can see the base interval and number of bars are separately defined. (Limit bar count and other settings)

Use the formula in the chart.

There maybe problems with Daily and above TF. This is working example of 15m chart. Even 5m is ok.
