Topic: customize Indicators
Hello,
unfortunately I cant find the Indicator data files which are preinstalled on FSB to build my own custom Indicators. Is this on purpose, or am I too dumb to find the files?

Re: customize Indicators
I tried to translate an Indicator
FSB says :
Custom Indicators
File name: steady bands neu.cs
ERROR: Obsolete format of source code in file [steady bands neu.cs].
Get a newer version from Code Repository.
Were is the mistake?

Re: customize Indicators
BTW when i install FSB pro are the indicators in new format already
or do I need to download them from repo and overwrite?

Re: customize Indicators
FSB Pro uses the same indicators as FSB v3.0 and FST v 3.0. There are problems with Spread Level indicator. Current WTF indicators do not work with FSB Pro. They can be fixed, but it's pointless since FSB Pro includes same functionality, but much better implemented. FSB Pro doesn't try to compose WTF. It loads actual data from desired period.

Re: customize Indicators
I tried it with a 2nd Indicator, but I made a mistake again. Could you take a quick look were the mistake is, please.
