What's Included?

The TWFX Volume Dots Study contains the following related studies –

  • TWFX Volume Dots
  • TWFX Delta Dots
  • TWFX Volume Dots – LW
  • TWFX Delta Dots – LW

LW suffixed studies use only native Sierra Chart drawing output styles and are subject to a number of limitations when compared to the non-LW studies. LW studies are included specifically for compatibility with OpenGL graphics.

TWFX Volume Dots and TWFX Delta Dots are both configured for high performance chart drawing, they offer a significant performance improvement* vs. the LW suffixed versions (when not using OpenGL graphics).

*Reductions in chart drawing times of greater than 80% were observed during testing, actual improvements may vary depending on computer software / hardware configuration.

    What can I say, added it to my numbers bar chart and immediately, saw the benefit 🙂

    As the delta or volume starts to increase, the bubble starts to build so imemdiately you can see where absorbtion/interest etc is taking place.

    The ability to show both bid/ask delta as well as volume as a pie/or as gradient/or as split relaly adds to the information (compared to just plotting the bubble with the dominant side – although this is available too)

    As a long term user of Sierra Chart I know a good deal when I see it (espcially if you are interested in trading order flow).

    Had a 15 day trial, after two days, purchased it outright.
