Using iStochastic

[Ingvar Engelbrecht]

I am converting my EA to  MQL5;

I hit a stumblestone on how to use iStochastic.

I found examples on how to setup an handle for the indicator So far so good.

So I got the handle.  Now I just want to retrieve the signal line value for the last closed bar.

Examples I have found  show how to use the  iStochastic in an Indicator and putting the complete data into a buffer.
