I think you are right. The rules are very similar for all instruments traded.
Incidentally, and I hope this is not off topic, but What about the monthly T2W currencies competition ?
Obviously it is up to the participant to choose pairs in which to trade, but is there any restriction on the number of trades intraday or daily ?
Is scalping allowed, for example ?
Some things to consider if you decide to scalp:
Trade only the most liquid pairs.
Pairs such as the EUR/USD, GBP/USD, USD/CHF, and USD/JPY offer the tightest spreads because they tend to have the highest trading volume. You want your spreads to be as tight as possible since you will be entering the market frequently.
