Nasdaq- Where to sell?

Since May Nasdaq has traded in a rising wedge formation.
Now the pattern is finally broken to the downside and the price should fall from now on.
A correction of the last 2 trading days drop is not out of the question and this can give sellers a good opportunity for short trades.
I m looking at around 15300 for my sell trades and as a target 14k support for an 1:3 R:R
