We are going to require a commitment from these seemingly hostile Countries that they will neither create a new BRICS Currency, nor back any other Currency to replace the mighty U.S. Dollar or, they will face 100 per cent Tariffs, and should expect to say goodbye to selling into the wonderful U.S. Economy."

Note that yesterday's peak occurred at the falling 20-day average, which for the day lies near 23300, so that will be the immediate hurdle, which, given Gift nifty's 180-point jump should give way" said Akshay Chinchalkar, Head of Research, Axis Securities.
