S&P500 : The completion of the Diagonal pattern

In240 minutes chart of the uptrend from the range of 3511 to 3833 is in the form of 3 waves which confirms the scenario of the formation of the Diagonal pattern.
Currently, to get the the confirmation of the downtrend,the price should not cross the range of 3841,because the 3rd wave should not be shorter than the other waves.
By crossing the price from this range,this scenario will be violated.
Thee confirmation for this pattern will be received by the formation of 5 descending waves,and by crossing the price from the range of 3660.
According to monitored position, personally,I set the short order.
By considering the RSI you can also see the convergence
