it seems like it's on it's fourth wave and there is a nice rally going to happen but it might be a trap and all this move from 15,200 to almost 18,000 is just a rebound (wave B) for more worst correction .(wave C).
So my suggestion is wait until it confirm the move
support 17,150 any close in or below this point would be a confirmation to a move heading below 15000 with a stop to re load at 16,255 .
resistance 17,979 any close near to this area go long 19,333 with a stop to re load at 18,500
