need help with mt5 ea codes.

New comment
 

Hi. I'm new to MT5 coding. I migrated from MT4 and found out really quick that MT5 is totally different from MT4. anyways, this is my problem. My codes are below. the code is placed inside OnTick() but it stops after one of the OrderSend() are triggered. Please help me identify what is the problem here. I can't seem to find it. Thanks.

 

I'm expecting it to keep looping (every time a tick is received). do 1, 2, 3 and keep looping in 4. I expect to see a message " Stop Order Placed. Waiting for it to be triggered" every time a tick is received.

what happens is that once an ordersend() is triggered, the whole thing just stops. 

// Variables
int i;
ulong ticket;
bool ans;

string   Target = "EURUSD";
int      Direction;
double   Price;
double   Lot;
double   SL;

bool   Stop_Order;
double Lots_Size_to_Pad = 0.01;
MqlTradeResult result = {0};
MqlTradeRequest request = {0};
double Pips_Clearance;
double Spread;
double Trail_Clearance;
MqlTick Tick;
