Before you place a single Forex trade, you need to understand what price charts are showing you. This is not complicated, but it is foundational. Traders who skip this step rely on guesswork. Traders who understand it can at least make informed decisions, even if trading is still difficult.
The Three Chart Types
Line charts connect closing prices over time. They show the general direction clearly but throw away most of the price action data.
Bar charts show the open, high, low, and close for each period. More information than a line chart, less visually intuitive.
Candlestick charts are what most Forex traders use. Each candle shows the same four values as a bar chart but in a visual format that is easier to read quickly. Green (or white) candles mean the close was higher than the open. Red (or black) candles mean the close was lower than the open. The thin lines above and below the body are called wicks and show the high and low of the period.
Timeframes and When to Use Each
| Timeframe | Each Candle = | Best For |
|---|---|---|
| M1 (1-minute) | 1 minute | Very short-term scalping |
| M5 / M15 | 5 or 15 minutes | Intraday trading |
| H1 (1-hour) | 1 hour | Day trading, identifying trends |
| H4 (4-hour) | 4 hours | Swing trading |
| D1 (Daily) | 1 day | Position trading, big picture |
A common mistake for new Thai traders: watching only the 1-minute chart. The smaller the timeframe, the more noise there is and the harder it is to distinguish real signals from random movement. Start with the H1 chart to understand the direction, then drop to M15 to find your entry.
Support and Resistance
Support is a price level where buying pressure has historically been strong enough to stop the price falling further. Resistance is the opposite — a level where selling pressure tends to cap price advances.
To identify them: look for price levels where the chart has repeatedly bounced up (support) or been rejected down (resistance). These are not magic lines — they represent areas where significant numbers of traders have placed orders based on previous price history.
Reading Trends
An uptrend is a series of higher highs and higher lows. Each rally goes higher than the last, and each pullback stays above the previous pullback low. A downtrend is the opposite: lower highs and lower lows.
Simple test: draw a straight line connecting the recent lows. If the line points up, the trend is up. If it points down, the trend is down. If it goes sideways, there is no trend — the market is ranging.
Key Candlestick Patterns
Doji: Open and close at nearly the same price. The candle looks like a cross or plus sign. It signals indecision — neither buyers nor sellers won that period. Often appears before reversals.
Hammer: A candle with a very long lower wick and small body at the top. It appears after a downtrend and signals that sellers drove price down but buyers pushed it back up. Potential bullish reversal signal.
Engulfing: A large candle that completely covers the body of the previous candle. A bullish engulfing at a support level is one of the more reliable reversal signals in Forex.
Practical Exercise
Open a demo account at any broker (no real money needed) and look at EUR/USD on the H1 chart. Draw horizontal lines at any obvious level where the price has bounced multiple times. Then wait and watch whether those levels hold or break. This exercise alone builds more chart-reading skill than most theoretical explanations.
