When large trading positions are liquidated, they can cause dramatic price swings and potentially force other traders into automatic deleveraging. This occurs if the size of the liquidated position exceeds the market's capacity to absorb it.
To mitigate these effects, BTSE has introduced a Risk Limits mechanism. This requires traders with large positions to maintain higher initial margins and maintenance margins. The benefit is twofold: it lessens the likelihood of automatic deleveraging during large position liquidations and reduces the occurrence of liquidations at off-market prices.
You must manually increase your risk limit if you wish to maintain a position and open orders that exceed the limits of your current risk level.
Higher risk limits lead to increased initial and maintenance margin requirements, which narrows the gap between your liquidation price and entry price, thus heightening the risk of liquidation or forced market transactions.
Risk Limit Levels
There are ten risk limit levels, each requiring incrementally higher maintenance and initial margin percentages as the position size increases. In the BTC perpetual contract market, for instance, every additional 100K contracts you hold increases the required margins by 0.5%. (For other markets, refer to the risk limit information on the trading page.)
Here’s a breakdown:
When your combined position and new order size exceed your current risk limit, the system will prompt you to upgrade your risk limit level before placing the new order. Conversely, after closing a large position, you must manually lower your risk limit level to decrease the margin thresholds.
Current position: 90K BTC perpetual contracts
Desired additional contracts: 20K
Total: 110K (exceeds 100K limit)
In this scenario, you must increase your risk limit to the 200K level to place the new 20K order. After closing the 110K position, manually adjust your risk limit back to the 100K level to revert to the original margin rates.
