8 ERROR ON THE CODE FOR MY EA

GOOD DAY

I have created a robot using mql5 however though i have 8 errors and i tried everythin i can do but still failing.

Please advise on what to do, i am will to add more if someone can solve my issue.

PLEASE FIND THE CODE BELOW.

#include <Trade\Trade.mqh>

input int length = 22;

input float mult = 3.0;

input bool showLabels = true;

input bool useClose = true;

input bool highlightState = true;

input double lotSize = 0.1; // Lot size for trading

input double stopLoss = 50; // Stop loss distance in points

input double trailingStop = 0.3; // Trailing stop percentage

//+------------------------------------------------------------------+
