Yes, have been mulling this over just now.
But how do you know to go short at the higher Res, and not the middle one (as per your screenshot).
All I can think of is that you take a small speculative position at the middle line, then bail out if it goes higher. Then do the same at the upper line, and then add in as it goes in your favour.
OR, (something I could automate), to set a short "at the next lower line".
If price keeps going up, you set a short at the previous Res. If price falls back to the previous Res, you go short. Vice versa for longs. (As price falls and passes each Sup line, the next higher is the trigger for a long.)
In above screenshot, I would go short at middle Res line, with the upper acting as alert.
It is not obvious to me that the Res line, that was the trigger WOULD BE the trigger, for a short.
(because price could have moved higher to the Highs of 1.3000 over on Oct 21st.)
PS: congrats on the trade, if you went short at the upper Res line!
