From Monday we will begin sending alerts on USDINR.
Like the commodities, the USD INR orderflow is been programmed for swing trading and will help you if you want to consider holding the trades overnight.
The options are very liquid and should help overnight trades with these signals.
The lot size of the instrument id about 1000 and the margin required per contract is under 1500/-.
Your Relationship manager should help set you up with your existing NSE margins.
