# Widget
## Chart Terminal Widgets — Trader's Overview Guide
This document answers three quick questions:
1. What **widgets** (side panels) does Chart Terminal have?
2. What does each widget **show**, and **when** should you use it?
3. Which widgets should you **enable** for each trading style?
Widgets are **optional panels** that sit beside the chart (right side on desktop, full-screen on mobile). They provide real-time data — orderbook, liquidations, large orders, walls — that a plain candle chart cannot display on its own. Toggle them freely; only keep what matters for your current strategy.

### 1. Where to open widgets
* **Desktop**: click the **Widgets** button (grid icon) in the top toolbar → click any row to **toggle** it on or off.
* **Mobile**: open **More** → **Widgets**. Panels open **full-screen**; close with **back / X**.
* **Defaults**: `Order Book` + `Walls` They are on by default.
* **Persistence**: your choices are saved to `localStorage` per browser/device — they survive page reloads.
> When multiple widgets are open the chart **shrinks**. Don't enable everything — keep 2–3 panels that are actually relevant to today's strategy.

### 2. All 9 widgets at a glance
| Widget | Core data | Answers the question | Best for |
| ----------------------- | --------------------------------- | ----------------------------------------------------- | -------------------------- |
| **Order Book** | Live bid/ask | "What does the book look like? Spread tight or wide?" | All traders |
| **DOM Ladder** | Aggregated depth by price | "Where is size sitting?" | Scalpers, order flow |
| **Depth Profile** | Multi-exchange liquidity by price | "Which zones are thick vs thin?" | Intraday, swing |
| **Liquidations** | Liquidation distribution map | "Where is cascade risk hiding?" | All traders |
| **Trade Panel** | Full order form + on-chart TP/SL | "I need to enter and manage a trade" | Active position management |
| **Trade Button** | Floating quick-trade bar | "I need to fire fast" | Scalp, reactive trading |
| **Algo Signals** (DEMO) | Algorithmic order-flow signals | "Is any setup forming right now?" | Reference / demo use only |
> **Algo Signals** carries a **DEMO** badge — use it to preview the logic, not as a standalone live signal.

### 3. Each widget in detail
#### 3.1. Order Book
**Shows**: classic **bid/ask table** — price levels and sizes from top of book downward.
**What to read:**
* **Spread** (gap between best bid and best ask) — tight = good liquidity; wide = thin market or high volatility.
* **Top-of-book size** — volume waiting right beside the current price. A lopsided size → short-term pressure in that direction.
* **B/A/R/S metrics** in the top bar (when active): B = bid volume, A = ask volume, R = ratio, S = spread.
**When to use:**
* At entry: see whether your size will be absorbed immediately.
* Placing limits: pick a price level that isn't sitting behind a massive wall.
**Caveat:** the order book is **extremely fast and prone to spoofing**. Never make long-term decisions from a single snapshot — watch for at least 10–30 seconds to see the pattern.
***
#### 3.2. DOM Ladder
**Shows**: a **vertical ladder** — each row is one price level, bid/ask sizes in two side-by-side columns, **aggregated** by a price step.
**What to read:**
* **Columns growing/disappearing** as price approaches → who is actively providing or pulling.
* **Iceberg**: size at a single level keeps refilling every time it gets hit → a large hidden participant.
* **Thin zone**: levels with very little size — if a breakout reaches this zone, price moves fast.
**When to use:** scalping, reading tape flow, timing fills near large pending orders.
**vs. Order Book**: DOM Ladder is more visual for the **price ladder as a whole**; Order Book is more detailed for **top-of-book and spread**.
***
#### 3.3. Depth Profile
**Shows**: a **multi-exchange liquidity profile** along the price axis — usually rendered as a horizontal histogram (wider bar = more liquidity).
**What to read:**
* **Liquidity support/resistance** — thick zones are where price tends to bounce or, when broken, to accelerate through.
* **Liquidity gaps** — levels with very little size are "highways" that price blows through quickly.
* **Exchange breakdown** (if shown) — which exchange is absorbing and which is offering.
**When to use:**
* Setting targets/stops based on real liquidity rather than only technical levels.
* Breakout/reversion plays: wait for price to approach a thick band → decide to fade or follow the momentum.
***
#### 3.6. Liquidations
**Shows**: a **liquidation depth/heatmap** — estimated notional at each price level of pending liquidations.
**What to read:**
* **Large long cluster below price** → a magnet pulling price down; when hit, expect a cascade.
* **Large short cluster above price** → a magnet pulling price up; when hit, expect a short squeeze.
* **After a cluster is swept** (it disappears) → that zone becomes **new support/resistance** because the forced-trade pressure has been consumed.
**Combine with the Agg Liq histogram**: the Depth/heatmap tells you **where the magnets are**; the histogram tells you **when they are exploding**. See [`agg-liquidations-trader-guide` ](/terminal/widget/liquidation.md)for the full guide.
**When to use:** planning targets/stops, identifying cascade risk before entry.
***
#### 3.7. Trade Panel
**Shows**: a full order form (Market/Limit/Stop, TP/SL, size, leverage) + **TP/SL lines rendered directly on the chart**.
**When to use:**
* You're ready to enter and want full position management.
* Need to **drag TP/SL on the chart** to adjust dynamically as price action evolves.
***
#### 3.8. Trade Button
**Shows**: a **floating quick-trade bar** on the chart — Long/Short in one click, pre-set size.
**When to use:**
* Scalping where you need **one-click entry**.
* Reactive trading — reading tape and reacting instantly.
* When you don't want the full Trade Panel to eat up screen space.
**Warning:** a misclick = a real order. Set a **small default size** until you're comfortable with it.
***
#### 3.9. Algo Signals (DEMO)
**Shows**: **orderbook microstructure signals** (e.g., absorption, imbalance, iceberg detection) generated by the algorithm.
**When to use:** treat as a **reference hint**, cross-check against your own manual read.
**DEMO caveat:** still in testing — do not use as a sole signal for large size.
***
### 4. Picking widgets by trading style
#### Scalper (1–5 minute trades)
* **Enable**: Order Book, DOM Ladder, Trade Button.
* **Optional**: Whales Order (when you want flow confirmation).
* **Why**: you need tape + DOM in real time + one-click entry.
#### Intraday (15m – 4h trades)
* **Enable**: Depth Profile, Walls, Liquidations.
* **Optional**: Order Book (enable only right before entry).
* **Why**: decisions hinge on liquidity zones + liquidation clusters; execute via Trade Panel when ready.
#### Swing (1–3 day trades)
* **Enable**: Liquidations, Depth Profile.
* **Optional**: Walls (for macro picture).
* **Why**: you care about large clusters and key liquidity zones; you don't need a live order ladder.
#### Holding a position (risk management)
* **Enable**: Trade Panel + Liquidations.
* **Why**: manage TP/SL directly on the chart; monitor clusters that could trigger a cascade near your position.

### 5. Recommended layouts
**2-panel (recommended for most traders):**
```
┌─────────────────────────────┬────────────┐
│ │ Liquid- │
│ CHART │ ations │
│ │ │
│ ├────────────┤
│ │ Walls │
│ │ │
└─────────────────────────────┴────────────┘
```
**3-panel scalp:**
```
┌───────────────┬─────────┬─────────┐
│ │ Order │ DOM │
│ CHART │ Book │ Ladder │
│ │ │ │
│ [Trade Btn] │ │ │
└───────────────┴─────────┴─────────┘
```
**4-panel swing (wide monitor):**
```
┌──────────┬────────────┬─────────┐
│ │ Depth │ Liquid- │
│ CHART │ Profile │ ations │
│ ├────────────┼─────────┤
│ │ Walls │ Whales │
└──────────┴────────────┴─────────┘
```
> More than 3 vertical panels will compress the chart into a square. For 4 panels, use a monitor ≥ 27" or an **ultrawide**.
***
### 6. Common mistakes
1. **Enabling all widgets "just in case"** — chart shrinks, eyes get confused, decision-making slows.
2. **Reading Order Book from a single snapshot** — the book is highly dynamic; observe for 10–30 seconds before concluding.
3. **Trusting a large wall unconditionally** — walls can be spoofed; watch whether they get pulled as price approaches.
4. **Assuming Whales Order = smart money** — not always; whales get liquidated too, especially in cascades.
5. **Turning on the Trade Button without setting a small default size** — one misclick = a full-size order.
6. **Using Algo Signals (DEMO) as a sole trigger** — cross-check only.
7. **Mismatching widget data with your chart timeframe** — scalping on a 1m chart while reading a Depth Profile calibrated for weekly liquidity = noise.
8. **Forgetting to update widgets when switching strategies** — your scalp setup is still open while you're now swing trading.
9. **Confusing Liquidations Depth (this panel) with the Agg Liq histogram (chart indicator)** — both complement each other; neither replaces the other.
10. **Ignoring spread/latency on thin exchanges** — an order book on a small exchange can look deep but fills slowly.
***
### 7. Quick checklist
Before starting a trading session:
* [ ] What is today's strategy? (scalp/intraday / swing)
* [ ] Have you enabled the **right 2–3 widgets** for that strategy?
* [ ] Have you closed unneeded widgets?
* [ ] If the Trade Button is on, is the default size set small?
* [ ] Is the Liquidations panel in sync with your chart timeframe?
* [ ] Are you reading **settled data** (closed bar, orderbook watched ≥ 10s) or just an instant snapshot?
If any answer is "not sure," → fix the setup before placing any order.

### Appendix: Quick glossary
| Term | Meaning |
| ----------------------- | -------------------------------------------------------------------- |
| **Order Book** | Queue of pending buy/sell orders at each price level |
| **Bid** | Pending buy order (buyer waiting) |
| **Ask** | Pending sell order (seller waiting) |
| **Spread** | Gap between best bid and best ask |
| **Top of book** | Best available bid and ask prices |
| **DOM** | Depth of Market — how much size sits at each level |
| **Depth** | Total available size around the current price |
| **Iceberg** | Large hidden order split into small visible chunks, refills when hit |
| **Spoof** | Placing a large fake order then pulling it before it gets filled |
| **Liquidation cluster** | Group of positions close to liquidation at nearby price levels |
| **Cascade** | Chain liquidations — one triggers the next |
| **Absorption** | Counter-force absorbing liquidation flow while price barely moves |
| **Imbalance** | Bid/ask or buy/sell overwhelmingly one-sided |
| **Notional** | USD value = price × coin amount |
***
**Philosophy**: each widget is **one information layer**. Don't use them to "predict" — use them to **reduce uncertainty**. When multiple layers agree (price + orderbook + walls + liquidations) → high-quality setup. When layers contradict → stay out or cut size. The chart never lacks signals; discipline in reading them is what's rare.
