Although 50% of the stake has been cancelled, the full original stake is still shown as turnover in the MTS Console. However, the P/L (profit loss) figures of the displayed ticket have been updated according to the cancellation.

\ <br>

The **second cancellation request** cancels further 30% of the original ticket stake. Now the cancelled portion of the stake will increase to 80%, while 20% of the original stake will still be active.\
Since the request has to contain the latest intended percentage (usually the accumulated percentage of this and all previous cancellation requests), its value is : "percentage": "0.8".
