Auto MOB EFS not working

[laxmicc]

I was trying to use efs file of automob but it was showing following error-

C:\Users\abc\Documents\ICE eSignal\Formulas\Back Testing Examples\automob.efs, line 1: Error: Failed to call 'GetPivotsStudy': function is not defined (yet).

I am providing the efs program here as unable to upload efs file. file share link of the file is eSignal File Share - The App .

knowledgebase link for this efs is AutoMOB.efs – EFS (esignal.com)

Please help me out by correcting this efs.

Somehow made this efs working on 21 versin , but its plotting only 1 mob from Primary Pivot. Corrected EFS program below. Can someone modify it to work on Major Pivots as well.

//Check every line 1 by 1

Line 60 had an error from the original post, see below for the fix, this works, on setting up one mob

Elliott = AGet.elliottWaves(0,50,300,ELLIOTTWAVES_ORIGINAL,E LLIOTTWAVES_INTERMEDIATE);

Thanks Ainsley for correction. Can you help me regarding automated trading too?

The below links (highlight and then right click and open in new tab) have most of what you need in order to cut some code but you will need to review and learn Java and JavaScript along the way, Im afraid no shortcuts exist, other than you spending many hours learning how to do it.

No shortcuts to knowledge exist so all you need to do is sit down, open the laptop and start learning, start with the esignal courses outlined below and over a three month period you will be in a position to create something unique.

also, one of the most important things to learn is how to write up your solution in pseudocode, which is what you will need prior to any coding, this is where the real work is done, so review this carefully and write it up in logical segments as a word document that captures your design and solution in logical detail which is then used to develop code from


This link is where you need to start, All About JavaScript - The Foundation of EFS – EFS (esignal.com)

This is the high level view of the EFS content EFS (esignal.com)

This link has all the keywords to use and for review - Function Reference – EFS (esignal.com)

Begin your journey, no shortcuts exist, download visual studio, and add the EFS add on and get going with the examples eSignal provide and start peddling.

It may be annoyingly hard at first but it simplifies immensely as you keep going, so press on and move forward.

Automated trading is most certainly possible and eSignal have provided all the tools to get this done, lookup Buy and Sell as key commands under the reference section.

See below two examples that can also be used to test your design on the market, eSignal have provided an awesome tool that does all the analytics anyone could ever want as part of the program, lookup, from within the eSignal platform, Chart\Back Test Report

Strategy.doLong("Long Signal", Strategy.MARKET, Strategy.THISBAR); // Enter a long position

Strategy.doSell("Long Exit", Strategy.MARKET, Strategy.THISBAR); // exit a long position

lookup the example code and run it to review, you can find it under formulas\back testing examples

Hi Ainsley, Thankyou for your comprehensive suggestion regarding EFS development. I wish I could have got this advice 3 months back. I am not very good at writing the strategy on pseudo code (if possible pls share few pseudo codes with EFS for my better understanding). I don't know any programming language just learned basics of EFS and using it by modifying the basic studies provided by eSignal. Those guides will help me alot on the process of being a programmer for my strategies.

Regarding the mob it is potting 1 from primary pivot only, can we make it to work on major pivots as well?


Lucky [email protected]

[Ainsley]

here is an example of pseudocode

IF you are happy THEN
smile
ELSE IF you are sad
frown
ELSE
keep face plain
ENDIF

writeup your solution in a similar fashion, this is then used to code from

MOB's and Ellipses are great, I use them from the primary pivot, to go for more will give you a busy chart but each to their own, experiment is the way forward, get it working with primary and then tweak it
