Multi-symbol EA - For loop gets ignored almost completely

[Dinomayn]

Hello MQL5 forum I have a problem with my code. Hope someone can help.

When I run it through the debugger, I can see that the only line that gets executed in the for loop is the first line. The EA then ignores 'if(PositionGetSymbol(i) == SymbolOne){' and the rest of the first loop. It's a similar case for the second loop, where 'if(OrderGetString(ORDER_SYMBOL) == SymbolOne){' and the rest of the loop gets ignored. 

input int magicNumberS1LongOne = 11100;
input int magicNumberS1ShortOne = 12100;
input int magicNumberS2LongOne = 21100;
input int magicNumberS2ShortOne = 22100;

string SymbolOne = "AUDUSD.pro";

   double currentSlOne = 0;
   double currentPosUnitOne = 0;

void OnTick(){

   // Create integer variable for total long and short positions.
   int totalPositionsOne = 0;
   int totalPositionsLongOne = 0;
   int totalPositionsShortOne = 0; 
    
   //Create double variable for highest opening price for long positions and lowest opening price for short positions
   double highestAskOne = 0.0;
   double lowestBidOne = 1000000.0;
   
   // Use for loop to find total amount of long and short positions. 
   // The highest long positions and lowest short positions are also found.
   // Current Position Unit SL is set. 
   for(int i=PositionsTotal() - 1; i >= 0; i--){
      if(PositionGetSymbol(i) == SymbolOne){
         if(PositionsTotal() > 0){
            totalPositionsOne++;
            if(PositionGetInteger(POSITION_TYPE) == POSITION_TYPE_BUY){
               totalPositionsLongOne++;
               if(PositionGetInteger(POSITION_MAGIC) == magicNumberS1LongOne){
