Here's a Gom-based indicator to measure custom swing deltas. The original suggestion came from Schuster21 in timmyb's Prometheus thread. I thought it was a good idea, but wanted something 'lighter' than Prometheus. So I took the GomCDSMA, surgically removed the SMA material, inserted some mouse DNA from GomMP, and stitched the result together.
It requires both the Gom data framework and the GomHotkey manager in order to function, so I'm uploading it as a .cs file rather than a .zip file. If you want to try it, copy the file into your NT Indicators folder, then open it for editing within NT and compile it (F5).
Apart from visuals, there are two parameters affecting calculations:
"Include Start Bar" determines whether to start volume and delta calculations from the close of the start bar or from the previous bar.
"Use Highs and Lows" determines whether to use Highs and Lows for swing calculations and drawing, or the Closes. This does not affect the volume and delta calculations.
HotKeys:
Insert -- initiates Mouse tracking. Click on a bar to start a swing. Click on a later bar to end it, or, for live tracking, press Insert a second time and the swing will extend to the current Close and start live tracking.
Delete -- click on a swing between start bar and end bar to delete it.
Escape -- exits edit/mouse mode.
Ctrl - X -- Hide/Show toggle for all visuals.
The relative height of the mouse clicks determines whether it's an up swing or a down swing: if the second click is below the first it's a down swing, and vice versa. For live tracking, it's above or below the current price.
