When you go short on a forex, the first currency is sold while the second currency is bought. To go short on a currency means you sell it hoping that its prices will decline in future. In forex trade, whether you are making “long” (buying a currency pair) or “short” (selling a currency pair) trades, you are always long on one currency and short on another. Therefore, if you sell, or go short on USD/INR, then you are long on INR and short on USD. It means you expect the prices of INR (Indian rupees) will rise and the price of the USD (US dollar) will fall.
