How to Place, Modify, and Cancel Orders on the Chart in MT5 (iOS)
On MT5 (MetaTrader 5), you can place pending orders such as limit and stop orders directly on the chart, and modify or cancel pending orders. This article explains how to place, modify, and cancel orders from the chart on the iOS version (iPhone/iPad) of MT5.
Placing Limit and Stop Orders on the Chart
Tap the limit order icon in the upper right of the chart.
An order level line appears on the chart, along with the "Buy Limit (order type)", "SL", "TP", and "→" buttons at the bottom of the screen.

Slide the order level line to the level where you want to place the order.
Tap "Buy Limit" to specify the order type, and tap "SL" or "TP" to set the stop loss and take profit levels attached to the order.
Once the settings are complete, slide the "→" to the right to place the order.

Modifying Orders on the Chart
Tap the order level line on the chart; dots appear on the line.
Drag a dot to adjust the order and its attached stop loss / take profit levels (this is not finalized at this stage).
The "SL" and "TP" buttons let you add or remove the attached stop loss / take profit.
After adjusting, tap the arrow button at the bottom right to switch to the order modification screen.

On the order modification screen, check the details and make corrections if needed.
Tap the "Modify" button to send the changes.
Tapping "Delete" here cancels the order.

Cancelling Orders on the Chart
Tap the order level line on the chart.
Slide "Delete Order" at the bottom of the screen to the right to cancel the order.
