What Do Technical Screener Indicators Mean for Indonesian Stocks on Pluang?
Pluang's Technical Screeners rely on six standard chart-analysis concepts: RSI (a 0–100 momentum gauge), SMA / Simple Moving Averages (average price over 20, 50, or 200 trailing days), ADX (a 0–100, direction-neutral trend-strength reading), 52-week high/low (price extremes over a rolling year), Volume (today's shares traded versus the recent average), and the Golden Cross pattern (the 50-day moving average crossing above the 200-day). Each indicator answers a genuinely different question about price action — RSI asks whether a stock has moved too far too fast, moving averages ask what the underlying trend direction is, ADX asks how strong that trend actually is regardless of direction, and volume asks whether unusual interest is showing up right now. None of these indicators predicts the future; they all describe patterns in price and volume data that have already happened, which is why Pluang treats every Technical Screener result as a starting point for research rather than a signal to act on immediately.
Plain-language explanations of each technical indicator:
| Indicator | What it measures | How to read it |
|---|---|---|
| RSI (Relative Strength Index) | Momentum of recent price changes, scaled 0–100 | >70 typically "overbought" (may have rallied too hard); <30 typically "oversold" (may have fallen too hard); 50 is neutral |
| SMA (Simple Moving Average) — 20, 50, 200 day | Average closing price over the trailing N trading days | Price above the MA = uptrend bias; price below = downtrend bias. Longer MAs (200-day) move more slowly and filter out more noise than shorter MAs (20-day) |
| ADX (Average Directional Index) | Strength of the current trend, direction-neutral, 0–100 | <20 = weak/sideways; 20–25 = developing trend; >25 = strong trend; >40 = very strong trend |
| 52-Week High | Highest closing price in the past 52 weeks | "Near 52-week high" usually means within 5% of that peak — possible breakout setup or momentum |
| 52-Week Low | Lowest closing price in the past 52 weeks | "Near 52-week low" usually means within 5% of that trough — possible value setup or continuing weakness |
| Volume (today's volume vs 20-day average) | How many shares are trading today versus a typical day | 2× the 20-day average = unusual activity; could reflect news, a catalyst, or coordinated trading |
| Golden Cross | A specific pattern: the 50-day MA crosses above the 200-day MA | Historically a bullish setup signaling a long-term trend turning up, but it's a lagging indicator that confirms a move already underway |
| Death Cross (not used in Pluang screeners) | The opposite pattern — the 50-day MA crosses below the 200-day MA | Historically bearish; Pluang's current screener lineup does not include a Death Cross screener |
One caveat that applies to all of these: every technical indicator describes what price has already done, not what it will do next. Signals can fail, volume spikes can be coordinated trading rather than genuine demand, and trends can reverse the day after they look strongest — use these indicators as one input in your own research, never as a standalone buy signal.
Related questions:
Q: Why is RSI 70 the conventional "overbought" threshold, and why does Pluang use 75?
RSI was designed by J. Welles Wilder in 1978, and 70/30 became the conventional overbought/oversold thresholds industry-wide. Pluang's RSI Overbought screener deliberately uses 75 instead of 70 for a stricter, higher-confidence signal, meaning it flags fewer stocks but with a stronger overbought reading than the textbook default would.
Q: What's the difference between SMA and EMA, and which does Pluang use?
Simple Moving Average (SMA) weights every trailing day equally, while Exponential Moving Average (EMA) weights more recent days more heavily, making it react faster to new price moves. Pluang's Technical Screeners use SMA exclusively, so the 20/50/200-day figures you see reflect an equal-weighted average, not an EMA.
Q: Does Volume in these screeners count both buy-side and sell-side activity?
Yes. Volume measures the total number of shares traded, regardless of whether the trade was buyer- or seller-initiated. A volume spike on its own doesn't tell you whether buyers or sellers are winning the tug-of-war — you'd need to look at price direction alongside volume to infer that.
Q: Where does Pluang's technical data for these screeners come from?
Technical Screener data is calculated from Pluang's live market price feeds for Indonesian stocks, the same underlying feed that powers the Trade Page and stock charts elsewhere in the app — it isn't a separately sourced or delayed dataset specific to Screeners.
