Open capability gaps

Abstract

This page records a product research synthesis: roughly thirty concrete capabilities that traders, quant authors, and chart power-users still treat as missing or incomplete on mainstream charting and strategy hosts. It is not a shipped-feature checklist for AXIS and not a competitive teardown of any named vendor.

Use it when prioritizing AXIS surfaces (sources, streams, engines, strategy results, debugging, data plane). Items below are durable demand themes from community threads and documented hard limits—not a public vendor roadmap with delivery status.

How to read this list

TermMeaning here
Still openCapability is absent, plan-gated to a partial substitute, or still described as unreliable for professional use
Not a ranking pollNo single global leaderboard exists; order is thematic, then by how often demand shows up as trade-blocking
Status changesIndividual venues or UX affordances can ship later; verify against current product notes before treating any row as forever

Highest-pressure themes overall: true tick and order-flow data, portfolio-grade strategy tooling, live multi-bracket and automated execution, higher cloud/screener ceilings, and a real interactive debugger.


Order flow, volume, and tick data

#CapabilityWhy it stays open
1True tick volume under volume profiles (including reliable delta)Profiles over the same range can disagree on buy/sell aggression; many treat minute-aggregated volume as unsuitable for professional volume work
2Real volume footprint with aggressor-tagged printsSynthetic or approximate footprints are still not trusted next to tick-native tools
3Transaction-level order-flow viewingCharts that are primarily bar/minute-based cannot show trade-by-trade flow without true tick history

Live trading, brackets, and execution

#CapabilityWhy it stays open
4Multi take-profit / multi-bracket management on live broker routesMulti-exit levels often exist in paper/simulators while live multi-exit brackets remain incomplete or broker-dependent
5Direct automated live order placement from strategy scriptsStrategy engines commonly fill via a broker emulator; real exchange orders need external webhooks or bridges
6Unified routing of strategy orders through the same trading panel path as manual/paper ordersScript strategies and discretionary trading panels are often separate stacks

Strategy model: portfolio, hedge, and fill realism

#CapabilityWhy it stays open
7Native multi-symbol / portfolio strategy backtestingOne script run is typically bound to one chart dataset; multi-asset P&L is export-and-compare, not a portfolio engine
8Simultaneous long + short (hedge) on the same symbolPosition models are often single-direction at a time
9Positions in symbols other than the chart assetCross-asset entries from one strategy remain unsupported on many hosts
10Full tick-level historical fill realismFills usually walk chart OHLC with assumed open→high→low→close (or open→low→high→close) paths; higher-resolution path reconstruction is partial and often tier-gated
11Large trade histories without silent trimNon–deep backtests often cap order history (older trades dropped from testers); deep modes raise the ceiling but remain product-tier features

Script runtime, quotas, and tooling

#CapabilityWhy it stays open
12Higher unique multi-series / remote-series request ceilingsCloud hosts hard-cap distinct series fetches per script (plan tiers only raise the number)
13Higher total script wall-time budgetsEntire-run timeouts remain fixed per plan class
14Higher per-bar loop budgetsTight loop-per-bar limits reject heavy iterative logic
15Higher data, memory, and compiled-size capsLarge libraries and data-heavy studies hit opaque resource walls
16Large multi-symbol scanning without burning unique-request quotasDynamic loops still count each distinct symbol/timeframe against the unique ceiling
17Runtime profilers (wall time, memory, compiled size) before failureAuthors discover limits by rejection or runtime error, not by measurement tools
18Interactive step-through debugger with breakpointsOfficial debugging remains logs, plots, drawings, and chart colors—not a classic debugger

Script-driven screener constraints

#CapabilityWhy it stays open
19Multiple custom indicators per screener passMany screeners allow only one user script per screen
20Indicator-on-indicator composition inside the screenerNested studies are unsupported
21Custom timeframes in scripted screensNon-standard bars often unavailable
22Higher remote-series call counts inside screener scriptsTypical caps are very small (single-digit)
23Lookback beyond a short trailing window (e.g. hundreds of bars only)Screen math is truncated to recent history
24Full input-type coverage for screener-hosted scriptsSeveral input kinds are unsupported in the screener surface

Chart UX and market coverage

#CapabilityWhy it stays open
25Stable, discoverable watchlist gestures (e.g. context-menu add)Removal or relocation of common chart chrome produces sustained restore demand
26Timely exchange / venue chart coverage when a market is popularCoverage gaps surface as high-engagement “still missing” demand until a data feed lands
27Sector / industry / theme heatmaps and similar multi-name overview boardsRecurring UX requests outside pure charting

Open script host vs general-purpose stacks

#CapabilityWhy it stays open
28External data sources, HTTP, and host APIs from inside scriptsCloud sandboxes intentionally block outbound and arbitrary I/O
29Databases, file I/O, and machine-learning libraries inside the script runtimeLanguage surface is chart-bound, not a general quant stack
30True custom UI and host programming beyond chart plots and fixed panelsOutgrow path is usually a multi-asset engine with live broker APIs outside the chart host

Themes for AXIS

These gaps map cleanly onto AXIS axes without implying any third-party product parity:

Demand themeAXIS lever
Tick / order-flow fidelityPluggable sources and streams with higher-resolution bars or trades when data exists
Portfolio multi-symbol strategiesMulti-source strategy evaluation and results beyond single-chart P&L
Live multi-exit and automationOptional execution adapters / webhooks (explicit, user-owned—not silent live routing)
Runtime ceilings and profilersLocal and Worker engines with measurable limits you control
Interactive debuggerStep and pin tooling against the active engine (see UI debugging surfaces)
Screener scaleOffline or self-hosted scan loops unbound by a single vendor’s cloud quota
External data / ML / DBHost bridges and plugins—not inventing closed chart-host APIs

Note

AXIS remains a composition host: sources load history, streams advance the present, engines evaluate scripts, storage holds libraries. Capability work should preserve that separation.

Research notes

  • Synthesis date context: community and documentation signals through early–mid 2026.
  • “Still open” means encoded as present limits or still treated as incomplete in high-engagement demand—not items already reversed by later product notes.
  • Engagement is qualitative across forums and social posts; it is not a weighted global survey.
  • Plan-gated historical depth and deep-backtest order ceilings partially address older “more bars / more trades” asks; those are de-emphasized relative to portfolio, execution, order-flow, and tooling gaps.
