Nifty Approaching its channel Upper end

Nifty is trading in a channel where it retraced back nearly 550 points exactly from the lower trend line of channel ,as expected now all eyes are at the upper trend line of this channel ,if price approaches to it than we can see a fall from there .There is a major resistance level is place at 17600 which was a crucial support earlier.
If you were in a buy trade as am I than wait for it to test the upper trend line till than keeping a trailing stop loss is a better option.
