This calendar spread is currently close to an extreme again. If you want to short this spread to exploit the mean reversion effect be careful because this specific spread (September/October) is only tradable until mid of August!
A first take profit could be the level of $1 if you are conservative. If you are a bit more aggressive then you can close the trade at a lower level, for example, $0.80 or even lower.
