Charts are not enough. Scalping method is great but if a newbie does not know when to use it, when to stop scalping as well as trading before a massive movements of market, all temporary earned profit will be lost.
Beyond the chart, newbies must look at walls. Walls don't stay permanently but they're signals of possibly big movements in the future. If the market has massive movements, it will move to where the walls are staying.
It depends on the specific strategy and on the signals that the trader relies on. For me personally, graphical analysis shows all the information I need. On the chart, I look at the levels, local and global, also switching between timeframes, from 5m to 1d. I didn’t look at the walls, and indeed at the glass of applications 4 years ago, I don’t look now, I don’t need it.
