Users must manually raise and lower their risk limit. The risk limit button is on the right under the leverage slider.
Your current risk limit usage will be indicated. If you place an order that would bring your usage above your risk limit, you will be prompted to increase your risk limit, and then you can resubmit your order.
At each step, the maintenance and initial margin are raised by the base maintenance margin. For example, with XBTUSD the base maintenance and initial margin are 0.50% and 2.00% respectively.
The calculation for the new maintenance margin becomes
0.50% + ( # of Steps * 0.50% ) and the new initial margin becomes
2.00% + ( # of Steps * 0.50% ). Hence we can create a table as such:
|Position Size||Maintenance Margin||Initial Margin|
|< 100 XBT||0.50%||2.00%|
|< 150 XBT||1.00%||2.50%|
|< 200 XBT||1.50%||3.00%|
|< 250 XBT||2.00%||3.50%|
A trader has a XBTUSD position worth 80 XBT. The current maintenance margin requirement is 0.5% (0.4 XBT), and current initial margin requirement for new orders is 2.00% (50x leverage).
The trader wishes to places a new order of 50 XBT on XBTUSD that would increase his position to 130 XBT. Because their account is now greater than 100 XBT, he is 1 step above the Base Risk Limit of 100 XBT. The trader thus increases their maintenance and initial margin to the next step (<150XBT) to 1% and 2.50%, respectively.
