To prevent a stop out, traders should closely monitor their open positions and ensure that there is always sufficient margin in their account to support their trades. This involves managing the size of their positions, using stop-loss orders to limit potential losses, and avoiding over-leveraging their account. Our specific stop out threshold is set at 20%, meaning if the margin level falls below this percentage, open positions will begin to close automatically. It is also prudent to keep additional funds in the account to buffer against market volatility and margin expansion, which can occur during periods of high volatility or when holding positions overnight and over the weekend.
