Hi there dear friend apprentice.
I was able to get the code for the real Weis Wave indicator. It is for ninjatrader, but you can check the code and then make a MT4 version using this code, let´s see how it compare with the others.
Also, I ask you please to code a Multicharts version too. It says that it is compatible with easy coding languages or something like that:

You can download the Multicharts from their own website (so you can use the indicator editor, which is similar to metaeditor), you have a 30 day trial but if you want I can teach via private message a trick that will make it run forever.

I have attached the ninjatrader code to this post.
