Tensorcharts is able to provide is a heat maping for breaking down key walls & support. Basically, when there is a large position within the market bars of different colors are representing these orders above & below the chart. Almost like a more in-depth Ichimoku cloud for anyone that finds that type of trading interesting. This indicator can also be a really good tool for deciding at what levels you should stop loss or shoot for before consideration
