If you set a stop-loss order 50 pips away from your entry price while trading 1 standard lot (which is 100,000 units) in the forex market, the amount you will lose can be calculated based on the pip value for the currency pair you are trading.For most major currency pairs, the pip value for 1 standard lot is typically $10 per pip. Therefore, if the currency pair moves against you by 50 pips, your loss would be calculated as follows: Loss=Pip Value×Number of PipsLoss=Pip Value×Number of Pips

Loss=10 (USD per pip)×50 (pips)=500 USD 

Thus, if the currency pair moves against you by 50 pips while trading 1 standard lot, you would lose $500.
