I don't know the calculation inside CheckLowest() function, but try to assign it to some variable and see

double abc, xyz;
abc = Bid;
xyz = CheckLowest();
Print(abc+"<"+xyz); 
if (abc < xyz)
    {
    Print("Buy!!");
    }

Because the code you have there did not output what you have shown to the log . . .  Print() outputs 4 decimal digits,  what you have there in the log is 8 . . .  that code did not produce that log output . . . .  find the code that did.

Sorry Raptor, you're wrong this time. If the code was

Print(Bid,"<",CheckLowest());

you'd be correct but double+string expands to 8 digits.

I'm happy to be wrong,  it means I learn something in the process . . . .  so the implication is that  CheckLowest()  returns a string and that would explain why the  <  comparison fails and   Buy!!  isn't printed  ?

What is the return type of CheckLowest() function ?, Is it string or double ?

If its double, it should print correctly

double abc, xyz;

abc = Bid;
xyz = CheckLowest();

Print(DoubleToStr(abc, 8) + "<" + DoubleToStr(xyz, 8)); 
if (abc < xyz)
    {
    Print("Buy!!");
    }

 But if its a string, well, you can not compare double with string, can you ?
