# Drawing on the chart (/platform/quant/drawing)
Ask Quant, our coding agent, to analyze the chart in front of you and it marks it up in Vela, our next-generation charting platform, as real drawings you can move, edit, or delete. One request can combine several concepts, so a single sentence can produce a full morning markup.
Open the market and timeframe you want on a candle chart, and click it so it's the [active chart](/platform/charts/introduction#the-active-cell). To mark up another chart in the layout, name it, for example "the ETH chart on the right".
Name the concepts in your own words: "mark the FVGs and liquidity", "draw the dealing range", "show me the NY killzones". Before it draws, Quant says in one line what it's about to mark, then a cursor places each drawing on the chart.
Each label shows its level, for example "Range High (21,435.00)", and the reply quotes the prices, so you can check every drawing against your chart.
## Every level sits on your chart's own candles [#every-level-sits-on-your-charts-own-candles]
Quant places each drawing on the candles that formed it: ask for a dealing range and the high and the low land on the bars that made them. A level is never estimated from a screenshot.
* **Closed candles only.** A level doesn't shift while the current candle is still forming.
* **Redraws replace.** Asking for the same concept again replaces Quant's earlier markup of it, once the new version has landed.
## What Quant can mark [#what-quant-can-mark]
### ICT and Smart Money Concepts [#ict-and-smart-money-concepts]
| Concept | What lands on the chart |
| -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Fair value gaps** | Bullish and bearish gaps with their consequent encroachment (CE), and inversion FVGs |
| **Liquidity** | Buyside and sellside liquidity, including equal highs and lows |
| **Market structure** | Break of structure (BOS) and market structure shift (MSS) |
| **Order blocks** | Order blocks and breaker blocks |
| **Dealing range** | The range split at equilibrium into premium and discount, with the OTE zone. Name a high and low to use your own range. |
| **Opening gaps** | The New Week Opening Gap (NWOG) and New Day Opening Gap (NDOG), on markets that halt between sessions. A 24/7 market has none, and Quant says so. |
| **Killzones** | Asia, London, NY AM, NY Lunch, and NY PM, or windows you name, in New York time |
| **ICT macros** | The London, New York, and last-hour macro windows |
| **Key levels** | Previous day and week high and low, the New York midnight open, and Asia, London, and New York session highs and lows |
### Classic technical analysis [#classic-technical-analysis]
| Concept | What lands on the chart |
| -------------------------- | --------------------------------------------------- |
| **Support and resistance** | Zones built from clustered reactions |
| **Trendlines** | Rising support and falling resistance lines |
| **Chart patterns** | Channels, wedges, and triangles, named on the chart |
| **A trader's range** | The range marked 1 / 0.5 / 0, with extensions |
### Your own scenarios [#your-own-scenarios]
For the setup you're discussing, Quant can draw its own read of the chart:
* Levels and zones: targets, entries, invalidation
* Projected paths: a scenario drawn as an arrowed path to a target
* Trendlines and channels
* Fibonacci retracements
* Text notes, such as a numbered setup
* Vertical lines at a time
* Long and short positions with entry, stop, and target
## Sessions follow the market [#sessions-follow-the-market]
Previous-day levels, opening gaps, and killzones use each market's own trading day:
| Market | Trading day starts |
| ------------------ | ------------------ |
| CME futures | 18:00 New York |
| Spot forex | 17:00 New York |
| US stocks and ETFs | The calendar date |
| Crypto | 00:00 UTC |
US early closes, such as Black Friday, Christmas Eve, and July 3, are known, so a shortened session is treated as the short session it is.
## Example prompts [#example-prompts]
Ask in your own words. These are starting points:
* "Mark the fair value gaps since today's New York open, with inversions."
* "Show buyside and sellside liquidity on this chart."
* "Mark market structure and the order blocks behind the last break."
* "Draw the dealing range with OTE."
* "Show today's killzones and the midnight open."
* "Where are the support and resistance zones on the daily?"
* "Draw the trendlines. Is this a wedge?"
* "Map the range from 64,200 to 67,900 with extensions."
* "Draw a bullish continuation scenario to 2,925 with a setup note."
* "Show a long from the CE with a stop under the order block and a 2R target."
* "Remove your order blocks and keep the rest."
## Edit, remove, and clear [#edit-remove-and-clear]
Quant's markups are regular [drawings](/platform/charts/drawings#drawings-by-quant). Move, recolor, hide, or delete them like your own; a label follows its drawing. They save with the [workspace](/platform/workspaces).
* **Clear Quant's drawings** appears on a chart while it holds any of Quant's drawings. Click it to remove all of them from that chart at once. Undo brings them back.
* **Ask Quant** to remove one concept ("remove the order blocks") or everything it drew, on one chart or on every chart in the layout.
Your own drawings are never touched: clearing and removing only apply to what Quant drew.
## Draw or write a script? [#draw-or-write-a-script]
Quant can answer the same question two ways: as a markup on the chart or as a script. A markup is analysis of the chart as it is now. It does not update when new bars arrive.
| You want | Quant |
| -------------------------------------------------------------------------------------------------------------- | --------------------------------------------- |
| Analysis of the chart right now: today's levels, the current structure, a scenario, a walkthrough of a concept | Draws it on the chart |
| Something that updates on every new bar, repeats across all of history, drives alerts, or can be backtested | Writes a script, or adds one from the Library |
| An indicator or a strategy, by name | Writes a script |
For a live concept, Quant looks for an indicator in the [LuxAlgo Library](/platform/charts/indicators#luxalgo-library) first, so you start from a published tool before anything new is written. When the other answer would help, Quant offers it in one line, for example "Want this as an indicator that updates live?" See [Making indicators](/platform/quant/indicators) and [Making strategies](/platform/quant/strategies).
## Limits [#limits]
* Up to **60** drawings per request, and up to **150** of Quant's drawings per chart. Past that, Quant asks you to remove some first.
* **Stop** takes back a half-finished markup, and switching the symbol or timeframe mid-drawing leaves nothing behind on the chart.
* In [Replay Mode](/platform/charts/replay), Quant reads the chart as of the replay point.
Quant doesn't mark up Heikin Ashi charts, because those candles aren't the real prices. Switch the chart to candles and ask again.
See the [FAQ](/platform/quant/faq#limits) for every limit in one place.
