Grape is an amazing tool to show when to open short position.

Each time MACD and SAR             change to show a downtrend, we can be pretty sure about a big crash/ correction.

We are actually in a critical area on the 3h graph, it prouved to be really reliable these days and we should fall soon.

Edit : Buy in target is the 400-450$ area ->
