# Trading Page
The trading page is the core execution interface for perpetual futures in H4.
| Section | Purpose |
| ----------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Header | Shows current PnL on the left, trade notifications on the right, and a share button. The share button can share the chart, the DOM, or the open position. |
| Main chart section | Displays the asset price chart. The chart can be expanded or switched into the DOM using the controls in the bottom-right corner of the chart. |
| Timeframe and asset selection | Lets the user change the chart timeframe or search for and switch to another asset. |
| Balances | Shows total account value and available balance. If the current margin asset is not Cash and that asset balance is below $10, tapping the Available area opens an inline swap from Cash into the margin asset. |
| Positions and orders data | Appears when a position is open or orders are resting. This section surfaces key data and provides quick actions to cancel all orders or close the position. |
| Settings | Lets the user switch margin mode between isolated and cross, and enable chart enhancements such as trades heatmap, L2 book, and crosshair. |
| Asset and market data | Shows asset-specific and market-wide data for the selected instrument. |
| Controls section | Lets the user place Long and Short orders, set size, and set leverage. |
### Chart settings
The chart settings section supports three optional visual layers:
* `Trades heatmap`, which overlays candles with trades and trade value
* `L2 book`, which adds the L2 order book to the right side of the chart
* `Crosshair`, which enables candle inspection on the chart
