# Chart Trading
H4 supports direct chart trading through touch gestures designed for fast placement and adjustment.
### Limit orders
Long-press on the chart to start placing an order.
A long-press below the current price starts a buy order. A long-press above the current price starts a sell order.
While placing the order, drag vertically to choose price. Drag left or right to adjust order size. The order can be released at any price on the chart.
The review panel can then be used to modify size and limit price.
If the order is opening a new position, the review panel can also attach TP and SL instructions that activate after the opening order executes.
If a buy order is released above the current price, or a sell order is released below the current price, H4 converts it into a trigger order. Otherwise, it is submitted as a standard GTC order.
Long-pressing an already placed order lets the user modify it by dragging it to a new price and releasing.
### Scale orders
H4 supports an `Open gesture` for scale orders.
While placing an order, adding a second touch splits the order into multiple smaller child orders so the entry can be distributed across a range.
When one touch is released, H4 enters cubic mode. Dragging up or down then adjusts the cubic distribution of those child orders.
### Cancel order
Double-pressing a resting order cancels that order.
### TP and SL
Long-pressing the entry price lets the user place a Take Profit or Stop Loss directly from the chart.
