just overall the theme of it is depressing makes me wanna jump out of a highrise building,
also i have no idea how to navigate it looks overly complicated (if your target was pro trades then sure my opinion shouldnt matter since im a noob)

not the most appealing to look at visually

The Heatmap I'm talking about has been "the latest greatest tool available to traders" for the last couple of years. If you look back at the history of it when indicators like MACD first came out snake oil salesmen were selling it for $10k. Then the chart package makers started to include it free, so the snake oil men moved on to the next big thing, rinse repeat.
I'm aware of Bookmap Xray https://bookmap.com/ $49 - $99 a month, being one of the first, now everyone is doing it and it'll be free in all charting packages in a couple of years.
In the end, all Heatmaps are is a visual representation of where orders were and that information is of no use to a trader at all. What I want to know is what orders are there now and do they get filled. So whether it's a chart of what trades occurred in the past or what orders were in the past I don't want to know.

DoM is the trading interface. TT that I mentioned before call it MD Trader but they get very protective of their copyright and patents so everyone else has to call theirs a DoM.
They show all the information a trader needs in numerical form and that's all the pro trader will look at.

Not that I can find right now, I'll have a deeper dig, but this mainly comes from conversations with traders.

Edit: I found a decent review of Bookmap Xray https://www.tradingschools.org/reviews/bookmap/
tl;dr

That's Ok, I wasn't thinking you selling anything. I have experience from many years in investment banks and know some professional traders in prop shops. Every single one of them trades purely from a Depth of Market. That shows bids, asks, volume at price and cumulative trades at the current price. They only use charts to make a note of possible support and resistance areas first thing in the morning before they start.

Heatmaps are just the latest in a long line of snake oil being sold to retail traders. How can knowing where there were some orders that got pulled previously were help you? The only thing that matters is what is happening right now. Are orders getting filled or being pulled, are there icebergs producing orders as fast as the ones you are seeing being filled. These are the only things that will tell you what is happening now so you can make a good guess what will happen next.

If you want to see how pro traders do it I think you can find youtube videos by a guy called John Grady who is about the only trading educator I know of with prop trading experience and who is an actually profitable trader. (I'm not recommending any of his services, I haven't tried them, I'm just pointing out the videos show what a pro is actually looking at).

Also if you want to have a go yourself you can sign up for a free demo account at Trading Technologies (trade.tt). It's the software the vast majority use. The demo is 10 minute delayed data from the CME and CBOT, but you can pretend it's live.

No, I wouldn't. Heatmaps, Heikin Ashi, Renko... etc. It's all nonsense really. None of them can be described as more accurate as they are just different visualisations of the same data. A lot of people got very rich selling the latest, greatest charting method and fancy indicators. If you have the chance to visit a professional trading firm you'll notice that none of them actually look at charts while they are trading.
I only use charts to determine support and resistance levels i.e. where did the market turn round last time. That doesn't mean it will again this time but I know it's an area that all pro-traders will be watching. Then I just watch order flow to decide if the level will hold or they're going to smash it for stops. That actually is all trading is.

A candlestick is actually displaying four pieces of information and has become much more commonly used than it's predecessor the OHLC bar. As the name indicates it shows the Open, High, Low and Close of each time period. The candlestick only varies in that rather than a tick for the low and high it colours in the body of the candle. There was a guy called Steve Nison who got very rich from marketing the idea he took from an ancient Japanese rice trader.

On your way leveling up you should take a peek at http://whalepool.io:8080/coinorama/ they got that Bits/Asks Ratio too, just classical line charts.
I will try to collect my experiences from using your charts. At the moment you are asking the first rookie strolling along for writing a fine manual and I am more like "wuuut? clueless..."
Will see what I can provide.

Complete new concept to my eyes, not seen anywhere before. Care to explain how to use these charts?
Difficulties in understanding...
I can see that downwards candle from 10 o'clock yesterday, 2017-10-15 where the lower part of the candle got the highest heat on Bitfinex (trading BTC/USD). From visual alone I would guess most of the volume tokes places after the drop in value, traders catching the falling knife.
Last hour of the day 23:00 the reversal candle has the hot end in it's upper side, again damping the move, this time the upwards motion.

That's the basic idea? Low temperature candles of small size suggesting a sideways motion following?
A readme or help button would fit in just fine anywhere on page.
