The idea is not all mine. In fact, I've heavily adopted this idea from another user here, named TAS (his idea here: https://www.tradingview.com/chart/BTCEUR...), pretty much copying his equilibrium and discount price levels.
Yet I strongly believe in a long term market trend (see also the latest advice given by Goldbug1 here: https://www.tradingview.com/chart/BTCUSD...) and thus incorporated the general uprise of BTC in this chart as well (the yellow diagonal surface), assuming the market price will eventually stabalise around that center line once again. With such a volatile market and uncertainty, I enjoy the feeling of looking a bit further ahead and making my trades with my horizon a little bit further up the road. Just like when skiing moguls, looking further ahead makes the bumps look smaller.
Curious to see what happens, BTC seems to dictate heavily the other coins like ETH and LTC as well. We'll see. Happy trading.
If it breaks through negatively, the next buy target is at 6500-7500 but that seems rather unlikely in my opinion.
