Strategy with custom toolbar button

nttoolbarbutton.cs

// source: https://ninjatrader.com/support/forum/showthread.php?t=23279

// Here's code that will add buttons you can use to place orders - so, it has to be in a strategy. You can add similar code to an indicator, but you won't be able to place orders from that code. I found the start of this on another site - I'll have to find the link to give credit where credit is due. 
// Please note - I found that in the button click events, the standard NT Open[0], etc. were not available. I had to cache values by updating private variables in OnBarUpdate() that I wanted to reference in the button click event code.
// I stripped out my own logic from the code in notepad. You may find a line of code or two that needs tweaking to get it to compile.
