eSignal Formula Script – EFS for short – is an extended version of JavaScript to which eSignal has added custom extensions. This tool gives you an edge in the world of charting and testing trading strategies. It is a formula engine that has powerful capabilities to help you develop, test and adjust your trading strategies.
And, EFS comes free with all versions of eSignal – from the end-of-day, delayed to the real-time, streaming versions.
You can create studies or modify pre-existing ones from the 100s available in our library. To help you do this, we have EFS tutorials to get you started. The library of pre-existing formulas is also readily accessible to you.
Our EFS user forums have a category specifically devoted to EFS where you can share formula studies with your peers and exchange "how-to" information, including sections on new EFS study suggestions and back testing using EFS.
Our Add-On Studies and Analysis page offers information on the third party proprietary EFS studies integrated or compatible with the eSignal and Advanced GET versions*, some free and some for an affordable add-on fee.
Those who prefer to leave formula development up to others with the specific expertise can take their trading strategy ideas to one of our select developer partners.
