Ren is setting up to be a great buy right now. There are two ways to approach this,
1. Buy it before break of trendline, you get a for a cheaper price but the risk is higher, next major support for REN is around the 0.88region chances of it dropping that low are not very high as the $1 mark also holds as a very good psychological level.
2. Buy it after clear break from the trendline (white arrow structure). if you choose to go this route, a retest of the trendline may not always happen and it can just jump past it.
