It depends on what pair you have traded, what the exchange rate is ? Not all pairs will give $10 per pip for 1 lot…! Also are you working pips out correct.?
Eur/usd is roughly $10 per pip, for 1 lot a pip is 0.00010 gain. So 1 pip is the 4th decimal when you measured your pips on MT4 if it says 13 that’s 1.3 pips not 13
