Counter trend hedge long on eurjpy if break above 120.35

I am short the EURJPY , but I do see a possible counter move to the up side if price breaks above 120.35 after todays bullish pinbar of support. If price breaks up I will be long with a take profit target at 121.35 as I expect the pair to continue to move in the direction of the main trend down from that point.
If price continues to move up. I will make 2R on the second (hedge) position and 0R (breakeven) on the first position.
If price moves down without triggering my hedge long, then I will make about 3.5R on my first position.
If price moves down after triggering my hedge long, then I will make about 3.5R - 1R = 2.5R.
If price moves exactly as I predict it, then I will make about 5.5R.
if my second position (hedge long) gets stopped out, then I will move the stop of the first position to 1R profit to counter the 1R loss on that second position. That way I will break even.
If I do not hedge, then I will either make 3.5R or 0R.
And by hedging this way I can make between 0R and 5.5R.

The first trade reached it's target, so I cancelled the order for the hedging.
