- MetaTrader charts are created using the bid price.
- Closing of buy orders are triggered by the bid price.
- You will see the chart line hitting the SL (Stop Loss).
The closing of sell orders is triggered by the asking price, which is not visible by default. That’s why stop losses of sell orders may occur on prices not seen on the chart.
You can activate the Ask Line by right-clicking on the Chart, select properties and enabling it.
