If

[CatDog]

Hello.

I will ask for help. What's wrong here?

   if (High[2]+0.0001==Low[1] && Close[2]+0.0001==Open[1]&&2*(Close[2]-Open[2])<Close[1]-Open[1]&& Close[1]-Open[1]>0.0025)

This is the code for USDPLN.

Why is it not working?

Below is the whole code.

... What's wrong here?

Your topic's title.

[William Roeder]

   if (High[2]+0.0001==Low[1] && Close[2]+0.0001==Open[1]&&2*(Close[2]-Open[2])<Close[1]-Open[1]&& Close[1]-Open[1]>0.0025)

1. Doubles are rarely equal. Understand the links in:
             The == operand. - MQL4 programming forum

2. Your constants (0.0001 and 0.0025) are 1 and 25 PIPs only on non-JPY pairs. Code breaks on JPY and exotics (e.g. USDZAR where spread is over 500 points,) and metals. Compute what a PIP is and use it, not points and not hard coded constants.
             How to manage JPY pairs with parameters? - MQL4 programming forum
             Slippage defined in index points - Currency Pairs - Expert Advisors and Automated Trading - MQL5 programming forum

3. You should be able to read your code out loud and have it make sense.

   You would never write if( (2+2 == 4) == true) would you? if(2+2 == 4) is sufficient. So don't write if(bool == true), just use if(bool) or if(!bool). Code becomes self documenting when you use meaningful variable names, like bool isLongEnabled where as Long_Entry sounds like a trigger price or a ticket number and "if long entry" is an incomplete sentence.

   This is unreadable:

   if(… && 2*(Close[2]-Open[2])<Close[1]-Open[1]&& Close[1]-Open[1]>0.0025)

   Write self documenting code.

   double pips25 = 0.0025;
   double upCandle2Range = Close[2]-Open[2];
   double upCandle1Range = Close[1]-Open[1];
   bool   smallUpCandle2 = 2*upCandle2Range < upCandle1Range;
   bool   largeUpCandle1 = upCandle1Range > pips25;
   if(… && smallUpCandle2 && largeUpCandle1) // This you can read and understand.
