What is the ruling on trading currencies using the spot system?

There is no harm in trading currencies, provided that the exchange takes place in the same session, that no financial leverage is used, and that the purchased currency enters your account and your currency enters the other party's account. The spot system means immediate or instantaneous trading, but it is not truly instantaneous; rather, it refers to the end of the month. It is impermissible to trade currency if the possession is delayed beyond the contracting session. However, a delay in bank registration for the conventionally accepted periods in trading markets is forgiven, provided that the beneficiary does not dispose of the currency during the forgiven period until after the effect of the bank registration is realized through the possibility of actual delivery.
