Group Description

I am maintaining this group as a repository for useful functions I have created since joining the forum. I am not a consultant or partner of eSignal, but biased a bit since I really like the Platform. I enjoy coding but choose not to make a living at it. Generally this fileShare has efs's that are either: 1) testing specific functions or; 2) using JavaScript functionality that I was trying to figure out at the time. In most cases, these efs's were written to be run in an advanced chart as stand alone entities. Sometimes the efs's used for testing does not include a main() or preMain() section. These are not essential for testing non-eSignal bar-based JavaScript. There are also more comprehensive efs's that were either written for others in the forum or myself. Recently, I have written a large number of simple efs's that utilize libraries that I have written. For the most part, the efs's are commented sufficiently to allow for their understanding. If you have any questions regarding the contents of this fileShare, please either PM or contact me on the forum.

You may see in the forum references to EFS1 and EFS2 functionality. There was a significant upgrade that occurred in 2005 where eSignal modified a number of EFS1 functions to make them easier to use. This transition to EFS2 also included a significant addition to the power of the platform to process alternate time frames and symbols within the same chart and/or efs. This is significant because many of the examples in the fileShare prior to mid 2005 were written using the older EFS1 platform. While backward compatibility was maintained, trying to modify these examples is significantly more difficult than re-writing them using the methods in EFS2. Not only that, the advanced functionality of EFS2 is not available unless re-written. Therefore, I recommend reviewing the eSignal KnowledgeBase so you can understand the differences so you know when you are looking at an efs that uses the EFS1 techniques. (there are some nice links in my forum signature area to EFS2 references and the EFS KnowledgeBase)

My focus has been on development of auto trading tools for my personal use. The examples that you see here have been developed towards that end. As a product of this effort, I have created several libraries that contain a number of the functions that I use on a regular basis. They contain some neat functionality that may be used by anyone. I have also run across a number of links to sites (coding reference or tutorials) that I found particularly useful over the past several years. Creating a listing to them here in my fileShare forced me to document and categorize them more succinctly than I would have otherwise. There are links to JavaScript, C sharp, Interactive Brokers and other resources.

I am rethinking my Libraries size. The larger they are, the harder they are to manage and make changes. My newest library takes a series object and calculating the regression and returning wrapped series objects. Still working on it...
