Dear Support,
I am trying to explore programming.
I got a sample from WIKI. See attached.

However when I tried to run it (Intraday, 5 mins timeframe), I got the following message.
Could someone please help to check the code.

2012-08-08 00:00:00 Exception java.lang.NullPointerException @ jforex.strategies.Stochastic.onStart(Stochastic.java:47)

Thanks so much in advance.

You need to open the chart for the selected instrument.
