S&D zones go hand in hand with Dominance + Momentum ; and Premium, Discount and Equilibrium concepts.
I. Supply and Demand Zones
Supply and demand zones, contrary to support and resistance levels, are areas (not finite numbers) on a price chart where the balance between buyers and sellers may shift, due to the presence of a lot of pending orders.
The Supply Zone is an area where sellers outnumber buyers, causing the price to drop. The Demand Zone instead, is an area where buyers outnumber sellers, causing the price to rise.
These areas are way more important than support/resistance ones and you can use them to spot potential reversals on the upside/downside. But how to individuate them?
Well, the idea is very subjective and traders use different S&D areas depending on their methodology and strategy (short/long term). To make it simple, I use the concept of Auction Market Theory, analyzing the balance or imbalance of the market.
In simple terms and as shown in this chart, when the market is balanced or in consolidation, at some point an impulse is being created by buyers or sellers.
The point from which the impulse starts, is called “origin point” and becomes my key reference to consider a potential demand zone.

For the same reason, I consider a potential supply zone from the start of the bearish origin point and thus from where the market was previously balanced.
That's how I find them and that's how I feel comfortable using them for my operations. But let's move to a practical example so you'll be able to understand the concept properly.

This is the daily chart of Bitcoin: I individuated the supply zone from the start of the first bearish origin point at approximately 53K (strong signal given the nasty nature of the red candle). You can see that over time the price has tested that supply zone and lately got rejected from it. On the contrary, I identified the demand zone starting from the bullish origin point at 40/41K, which has been validated by the price testing that zone with a long red wick and in Q1 2022 with the body of the candles.
2 key things to remember:
- I could have included the wicks of the candles in the demand zone and it would have still been valid.
- The more a supply or a demand zone is tested, the weaker it becomes as sell or buy orders get absorbed.

There's the general belief that every time a resistance or a support is being tested, the more it gets tested the stronger it becomes, but this statement is false, and I'm gonna show you why. Each support and resistance should be more properly considered as demand and supply zones respectively, where buy or sell orders are being placed. Every time the price of an asset tests multiple times a demand or a supply zone, that area doesn't become stronger but instead weaker. This happens because the preponderant part of the market is in control (buyers/sellers) and has the strength to continue to push the price toward a specific zone, absorbing the counterpart’s orders. It's like a war between 2 factions, where each attack kills a bunch of soldiers. How do you imagine the status of the faction constantly attacked? In shape? Of course not, and this causes the loss of the war.
In this example, you can see the price of Bitcoin testing the demand zone multiple times (notice the wicks that grab liquidity absorbing buy orders) also supported by the strong seller's momentum (velocity)).
At some point, those tests have “consumed” the buying pressure, leading the price to melt the demand zone.

Another clear example here : notice how the theory of “absorption” becomes true with the price testing the demand zone multiple times over months and then breaking below it with a strong bearish impulse.
The demand zone has in fact absorbed all the buy orders without being able to produce a strong uptrend.
This notion will help you identify key areas and evaluate your operativity based on the reaction, whether you're a trader or a long-term investor.

II. Dominance & Momentum
The ideas of Dominance & Momentum revolves around the classic market structure, with financial markets having 2 main directions for the trend:
- Bullish (higher highs + higher lows)
- Bearish (lower highs + lower lows)
Independently of the trend, buyers and sellers coexist in this market. Each high or each low can help us individuate where sellers and buyers have entered the market.
Key note: While wicks are important (liquidity grabs) we watch for the bodies of the candles to gauge relative strength: HTF closures above/below.
1. Dominance
The concept of dominance is extremely easy to understand : let’s see a concrete example. This chart shows a clear Bitcoin downtrend, with multiple lower highs and lower lows.
The directional bearish impulse starts from each high (red bubble) flashing more supply than demand and therefore pushing the price down.
At some point, buyers enter the market (green bubble) but cannot overcome the past sellers’ dominance zone (notice the lower highs) becoming a new level in which sellers push the price down again, so transforming into a new sellers dominance zone.

In the following chart however, we can see the price of Bitcoin violating the sellers dominance area, and that is our first sign that the tides are turning and buyers are starting to push to reverse the price.
In fact, with the developments of the price action, buyers have established new dominance levels. This is the concept of dominance utilized in trading and that can help you decide if it is worth selling or buying.

2. Momentum
"But mate, how can I have a stronger signal for buying or selling strength?"
With the use of momentum. Momentum in trading is nothing else than the speed with which the price reaches the sellers or buyers dominance:
- The less time it takes, the stronger the momentum for buyers or sellers
- The more time takes, the weaker the momentum for buyers or sellers
In this example, the buyers took 3 days to push the price higher (without violating the sellers dominance), while sellers just took 1 day to violate the buyers dominance.
This was another clear sign that sellers was in momentum and in complete control, helping us to consider staying away from the market or opening a potential short position.

Another example on the buyers side this time. Look at how fast buyers have broke above past sellers dominance areas:
Sellers weren't able to push the price down below the buyers dominance not even in 37 days, a clear sign of their loss of momentum and that buyers are in full control.

Dominance and momentum are 2 extremely simple concepts to master, but that put together with a solid analysis could make a huge impact on our operativity. Being able to decipher which is the main force in control of the market can help us to protect our capital or risk more depending on the current momentum. Even in this case, the rule is: the higher the timeframe, the stronger the signal. Always watch for D/W/M for having more reliability on the situation.
III. Premium, Discount & Equilibrium
We previously saw that every financial market moves from the simple law of supply & demand. From those levels, however, we need to elaborate a concrete strategy that can help us to make good financial decisions. What are in fact the 2 questions that meander in your mind when you look at a chart?
"At which price I would prefer to buy this asset?" "At which price I would prefer to sell it?"
Well mate, you don't need a genius to comprehend that you might want to buy low and sell high, right? This might sound trivial, but 90% of people lose money because they do the opposite. Getting down to brass tacks, technically speaking you want to:
- Buy at discount (low) -> below 0.5 Fibonacci
- Sell at premium (high) -> above 0.5 Fibonacci
- Have less interest in buying/selling at an intermediary price (equilibrium) -> 0.5
The more the price goes to the premium area, the more smart money will be inclined to sell. Conversely, the more the price goes down to the discount area, the more smart money will be interested in buying.

1. Equilibrium & Discount
Important disclaimer: I suggest you apply this concept to HTFs because that's the TF used by smart money and the one that rules the charts. In any case you can apply it even to LTFs, of course.
This is the Bitcoin weekly chart post bear market bottom : as you can see, the price begun to rise, initiating an impulse that surpasses the previous ones, flashing the start of an uptrend marked by a higher high (HH). Then, after the high of the impulse, a retracement phase took place, but until where specifically?
Using the Fibonacci retracement tool and by the principle of discount areas, we want to buy when the price falls below the equilibrium point (0.5), preferably. Personally, I would wait until the price reaches my area of interest, which corresponds to the yellow box (88.60/75/61.80) ~> you can set up these percentages on the Fibonacci retracement tool.
That's where I'm placing my buy orders in an HTF uptrend. In this case, the price of Bitcoin only wicked below the 0.5 not giving much time for people to take advantage of the discount zone.

Take note: the price doesn't have to fall back below the equilibrium point every time. There might be situations in which the price continues to rip regardless ,not offering the possibility to buy at a discount. It's always a matter of probabilities.
2. Equilibrium & Premium
Let's now see how this can be useful taking a downtrend example:
In this context, we had our previous BOMS (Break of Market Structure) which led to the bearish impulse. The price has lately jumped back above the equilibrium point entering the premium zone and providing a juicy area where to unload the bags. (88.60/75/61.80)
Even in this case, we don't have a guarantee on the price retracing to premium levels, but in case it does, our mind should be alert.
