Thank you. I find more interesting the ratio between buy and sell volume, I believe it can indicate the market sentiment despite overall price trend.

Speaking of support and resistence. I am about to release an update with heatmap of orderbook. It's much more powerful when it comes to support/resistence visualization.

Currently I would like to explore more this charting concept so no plans to connect other exchanges yet. If it proves itself useful I will surely add other exchanges and coins.
