Please take a closer look (carefully review) of the impact of the maker fee in function _updateStrategy
.
Specifically, where value
is addressed a second time:
// refund native token when there's no deposit in the order
// note that deposit handles refunds internally
if (token.isNative() && value > 0 && newOrders[i].y <= orders[i].y) {
payable(address(owner)).sendValue(value);
}
