Before analyzing a chart, an experienced trader asks two questions: how much does this asset move and how easily can I exit it. The answers determine everything else — trading style, position size, stop distance, and order type. Beginners skip these questions and pay twice: with stops that are too tight and inability to sell.

Volatility: Amplitude of Movements

Volatility is a measure of price variability over a period. An asset that moves 1% per day and one that moves 8% require fundamentally different handling, even if the charts look similar in form.

How to measure:

  • ATR (Average True Range) — an indicator showing typical daily movement in price units. ATR = 300 soums means the security typically moves 300 soums per day.
  • Historical volatility — standard deviation of returns over a period, in annualized percentage.
  • Daily range in percent — simplest reference point: the difference between maximum and minimum relative to price.

How Volatility Changes Trading

  1. Place stops in ATR units, not in 'round' percentages: 1.5–2 ATR from entry. A stop closer than one ATR will get whipped out by normal noise.
  2. Position size is inversely proportional to volatility. At equal monetary risk, a position in an asset with 8% ATR should be four times smaller than in an asset with 2% ATR.
  3. Volatility is cyclical. Range compression (low volatility) usually precedes a strong move; a spike often signals trend's end. This is a standalone trading signal.

Liquidity: Ease of Entry and Exit

Liquidity is the ability to buy or sell the required volume quickly without significantly affecting the price. Its indicators:

  • Trading volume — transaction volume per day or month;
  • Spread — difference between best bid and ask prices; on liquid assets — hundredths of a percent, on thin ones — percent;
  • Order book depth — volume of orders near current price;
  • Trade frequency — how many times a day trading occurs at all.

The Cost of Low Liquidity

On an illiquid market, a trader pays a hidden tax: spread on entry and exit, slippage on market orders, inability to quickly close a position on bad news, and broken stops — without matching orders, stops execute much worse than calculated or don't execute at all. This applies to local markets too: many Tashkent stocks trade with rare transactions, and the difference between liquid and illiquid securities is especially sharp here.

Rule for Thin Markets

Practical guideline: position should not exceed 5–10% of the security's average daily volume. Otherwise your own sale will crash the price. Use only limit orders — market orders on thin markets execute at random prices.

How Parameters Combine

  • High liquidity + high volatility — major cryptocurrencies, major currency pairs. Paradise for fast trading styles, but with strict risk management.
  • High liquidity + low volatility — large-cap stocks. Calm swing and position trading.
  • Low liquidity + high volatility — small altcoins, third-tier stocks. Most dangerous zone: moves are sharp, but you can't exit.
  • Low liquidity + low volatility — inactive local market stocks. Only long-term positions based on fundamental factors.

What to Check Before Trading

  1. 14-day ATR — and stop at least 1.5 ATR away.
  2. Average daily volume — and position no more than 5–10% of it.
  3. Current spread — if it exceeds expected profit on the trade, there's nothing to trade.

Conclusion: volatility and liquidity are the 'physics' of an asset, independent of your opinion. Adapt your stops, position size, and order type to them — and half of typical beginner losses disappear before chart analysis even begins.
