Each candle summarises a time interval. The body connects open and close; wicks mark high and low. Colour depends on chart settings. The same sequence viewed over five minutes or one day tells different stories. Start with the time scale and never treat a visual shape as certainty about the next price.
A market order seeks execution at the available price, which may differ from the last quote. A limit order sets a maximum buying price or minimum selling price and may not execute. Consider the difference between execution priority and a price condition. Liquidity, order size and volatility affect the outcome.
A conventional stop order becomes a market order when triggered. During fast moves or price gaps, execution may occur beyond the specified level. A stop-limit adds a price condition but may leave the position open. Check the rules and order types actually available on the platform.
