convert eSignal EFS indicator to the system FXCM uses

I presently use esignal which is pretty expensive and i use fxcm as a broker . Does anyone here convert efs indicator to an indicator that can be used on fxcm charts. What type or format do they use by the way?

All the other studies can be done but Advanced Get Studies are proprietary hence source code not available, but Esignal can be available for lesser price.
