Hi guys, when migrating my DEX contract which has 1 error which I don’t know how to fix as it underlines the last curly bracket of the contract brackets, and the terminal outputs
CompileError: ParserError: Function, variable, struct or modifier declaration expected.
--> project:/contracts/Dex.sol:76:2:

Compilation failed. See above.

This is my contract code.

uint i = orders.length > 0 ? orders.length -1 : 0;
if(side == Side.BUY){
while(i > 0){
if(orders[i - 1].price > orders[i].price){
break;
}
Orders memory orderToMove = orders[i-1];
orders[i-1] = orders[i];
orders[i] = orderToMove;
i--;
}
}
else if(side == Side.SELL){
while(i > 0){
if(orders[i - 1].price < orders[i].price){
break;
}
Orders memory orderToMove = orders[i-1];
orders[i-1] = orders[i];
orders[i] = orderToMove;
i--;
}
nextOrderId++;
}
}
Would appreciate it if anyone could help, thanks.
