Here's the translation into American English:

So here's the deal, many people are still confused about what SND or supply and demand in crypto trading is. In fact, this is one of the most fundamental concepts that can change the way we read the market.

Supply is a price zone where there are many sellers, strong selling pressure. When the price approaches this zone, there’s usually rejection because large investors start selling to take profits. Conversely, demand is an area where buyers are interested in entering; the price tends to bounce from here due to high demand.

Identifying SND is actually simple. Look at the chart, find zones where the price often reverses direction. For example, if Bitcoin rises from $25,000 and is repeatedly rejected at $30,000, that’s clearly a supply zone. Every time the price tries to break through, it drops again. That’s a sign that big investors are dumping at that level.

The same applies to Ethereum. If ETH drops from $2,000 to $1,800 but keeps bouncing from $1,800, then $1,800 is a strong demand zone. Buyers are interested at that price, they buy, and the price goes up again.

Volume is also important to watch. If you see high volume at a certain level, it’s likely a significant supply or demand area. Candlestick patterns also give signals; hammer, doji, or engulfing patterns often appear in these zones.

Why is this important? Because understanding SND allows us to set smarter entry and exit points. You can place limit orders in demand areas to get a good price, or set proper stop-losses near supply zones to protect your capital. The risk-reward ratio becomes more favorable.

But be careful, this isn’t a holy grail. Prices can break out from these zones, or even fake out — go up briefly then drop again. Market sentiment changes very quickly, especially in volatile crypto markets. Liquidity is also a factor; trading low-volume altcoins means these zones can be unreliable because whales can move prices easily.

The strategy I often use: don’t enter immediately. Wait for confirmation, see if there’s a reversal pattern or volume spike in the SND area. Once confirmed, then enter with proper position sizing. Don’t go all-in; spread your risk across multiple positions.

Risk management is key. Set stop-loss a few points above supply or below demand. If the price breaks out violently, cut your losses and move on. The crypto market is too unpredictable for ego.

So, in summary, understanding SND is a skill every trader must master. Combine this with other analysis, stay disciplined, and trading can become more consistent. I personally always cross-check with other indicators before executing trades in these critical areas.
