An E-micro is a futures contract traded on the Chicago Mercantile Exchange (CME) Globex electronic trading platform, that represents an even smaller fraction of the value of the normal futures contracts than the corresponding E-mini.
Currently, CME offers one E-micro stock market index contract, E-micro S&P CNX Nifty (Nifty 50) Futures, with a notional value of $2 x the S&P CNX Nifty index of Indian stocks,[1] and E-micro contracts for a number of currency futures pegged against the US Dollar (AUD, CAD, CHF, EUR, GBP, JPY).

Note that individual brokers may require different margin amounts (also called performance bonds).
