Why has the limit order/stop order/stop limit order I created been executed even though the price on the chart has not yet touched the limit price I set?

There is a possibility that your order will be executed even though the previous data record on the chart shows that the price has not touched the limit/stop limit price that you have specified. This happens because the crypto price that appears on the chart is determined by taking the volume weighted average of all market pair prices listed on the exchange for that asset.
