What Are the Broker & Foreign Screeners for Indonesian Stocks on Pluang?
Broker & Foreign Screeners are five Indonesian-market-specific filters that surface stocks based on broker trading concentration and foreign investor flow — two signals with no direct equivalent in Pluang's other, more global screener categories. The five are Foreign Uptrend, Positive Foreign Buy, Big Broker Accumulation, Broker Bullish, and Broker Bearish, and all five are new additions specific to Pluang's Indonesian Stocks Screeners rather than carried over from a generic screener framework. Three of the five (Big Broker Accumulation, Broker Bullish, Broker Bearish) key off Broker Index — the share of a stock's net trading volume captured by its top 3 brokers — while the other two (Foreign Uptrend, Positive Foreign Buy) key off Foreign Net Buy, the difference between foreign investor buying and selling volume on a given day. Because the IDX has relatively concentrated trading flow compared to larger markets, tracking broker-level and foreign-flow activity is a standard part of Indonesian retail investor research, even though these signals describe what already happened rather than what will happen next.
The five Broker & Foreign Screeners:
| Screener | Criteria | What it signals |
|---|---|---|
| Foreign Uptrend | Last-day foreign buy volume > average foreign buy volume over the prior 20 days | Foreign investors are buying more than their recent average — possible foreign demand building |
| Positive Foreign Buy | Top 50 stocks ranked by positive net foreign buy volume (refreshed daily) | The 50 Indonesian stocks foreign investors net-bought the most yesterday |
| Big Broker Accumulation | Broker Index ≥ 20% | A small group of brokers is concentrating buying activity on the stock — possible accumulation |
| Broker Bullish | Broker Index ≥ 20% AND current price < broker average cost | Brokers are accumulating below their own average cost — possible bullish positioning |
| Broker Bearish | Broker Index ≥ 20% AND current price > broker average cost | Brokers are distributing above their own average cost — possible bearish positioning |
Important reminder: all five screeners describe historical flow, not predicted future moves. Concentrated broker activity and foreign buying can reverse the very next trading day, so a match should prompt further research rather than an immediate trade.

Q: What does "Broker Index" mean in these screeners?
Broker Index is the share of a stock's net trading volume captured by its top 3 brokers, calculated as (top 3 broker net volume ÷ total net volume) × 100. A figure of 20% or higher suggests concentrated trading activity by a small number of the dominant trading houses on the IDX, rather than broadly distributed retail flow.
Q: What's the difference between Foreign Uptrend and Positive Foreign Buy?
Foreign Uptrend compares yesterday's foreign buy volume against each stock's own 20-day average — it's a trend signal specific to that stock's recent pattern. Positive Foreign Buy instead ranks the 50 stocks with the single largest net foreign buy volume yesterday across the whole market — a magnitude ranking rather than a stock-specific trend comparison.
Q: Are Broker Bullish and Broker Bearish designed as opposites?
Yes, by design. Both require Broker Index at or above 20%, but Broker Bullish only triggers when the current price sits below the brokers' own average cost — meaning those brokers are sitting on unrealized gains if price rises further — while Broker Bearish triggers when price sits above their average cost, meaning they're already in profit and may be inclined to sell.
Q: Why don't Broker & Foreign Screeners exist for other Pluang asset classes?
Broker-level concentration and separately tracked foreign investor flow are specific features of how the IDX (Indonesia Stock Exchange) reports trading data — other markets and asset classes on Pluang, like Crypto or US Stocks, don't have an equivalent regulatory data feed, so these five screeners are IDSS-specific by nature rather than by choice.
