Do the studies work on all instruments?

Our studies are designed for futures trading and work on any futures instrument supported by your platform.

Can I use the studies on multiple computers?

Your license supports up to 5 registered devices, but only one can be active at a time. Logging in on a new device will automatically end the session on your previous one.

What if I have issues or need help?

Join our Discord community for direct support. We have an active community and the team responds quickly. Most issues are resolved within hours.

What happens when platforms update?

We actively maintain compatibility with platform updates. If an update breaks anything, we push a fix as soon as possible. All updates are included with your license.

Reviews

Loved by traders.

“I know of and used dozens of orderflow based vendors and indicators. This is amongst the best, if not honestly the actual best vendor. This combines and improves upon all the aforementioned used indicators into packages at a mind boggling affordable price. The support is also second to none. They are also always looking to improve and adding extra orderflow ideas.”

The other side of the tape.

DDY reads the futures tape. Vexity reads the options behind it — dealer positioning, classified flow and the levels that positioning implies, computed live. Same team, separate platform.

vexityvexity.net

The whole option chain — every print, every strike, every expiry — normalised the moment it lands and resolved into exposure, flow and levels sub-second. It runs in the browser and streams onto the same charts you already run DDY on.

All 12 greeksPer strike and per expiry.

Dealer exposureGEX walls and the gamma flip.

Classified flowAggression, size, unusual prints.

VolatilitySmile, term structure, surface.

Live key levelsNever repainted after the fact.

Session replayScrub any past session.
