As there are two possibilities (although one may be unlikely) it is a good idea to setup an entry trade for the respective uptrend or downtrend right after the break from the pattern.
(a) The breakout follows an uptrend:
The holds a height of 0.661 (0.53%), which means that the consequent uptrend (or downtrend) must also hold a similar height. Therefore, a Take Profit at 125.273 would be a suitable choice as that is the equivalent 0.661 height Also, the at 125.273 was tested on 12th August which gives it a much higher significance.
(b) The breakout follows a downtrend:
The downtrend will hold a height of 0.661, which means that a Take Profit at 123.82 would be suitable for this short trade as the uptrend would be at a similar height and right above the 123.79 .
In case a breakout does not occur until later, a stop loss could be setup right above the 124.462 for a short trade (option (b)) and right below the 124.462 for a long trade (option (a)).
Overall, for a long trade (option (a)):
Stop Loss: 124.382
Take Profit: 125.273
Risk/Reward Ratio: 16.54
