Cayof your error report was very useful.
I found that "Illegal characters in path" error message was produced by a bug in the program.
It happens when there are different files containing one and the same indicator.
I'll update FSB Pro soon.
Spread Level.cs works only in FST for the moment. It can be easily fixed to use Spread parameter coming from MT4, but some brokers that use dynamic spread do not update it properly. Currently Spread Limiter uses Ask - Bid to calculate the correct spread. These params are not available in FSB and FSB Pro. I'll see how to fix it.
Adaptative Stochastic.cs - fixed.
Ergodic Indicator.cs - Fixed.
Hilbert Chanel.cs - Fixed
Finite Volume Element.cs - Fixed.
R squared.cs - fixed.
You can download these indicators from repo.
WTF indicators has some design issues. They can be fixed. I'll help if someone wants to make them compatible with FSB Pro.
FSB Pro has ability to use higher time frame for every Opening and Closing logic condition indicator. Soon I'll make it possible to trade with these options.
