What has a buy signal

Screening Filters

1. Monthly Average Dollar Volume ≥ $500,000

   • Purpose: Ensure the results are reasonably liquid and tradable.
   • Rationale:
     When you ask for instruments with a “buy signal,” those signals are far more reliable in markets where there is enough trading volume. A minimum dollar volume filter:
     • Reduces the risk of false technical signals caused by thin trading and wide bid–ask spreads.
     • Focuses the list on stocks where you can enter and exit positions more easily without large price impact.

2. Moving Average Relationship: PriceCrossAboveMA20

   • Purpose: Capture fresh, short‑term bullish signals.
   • Rationale:
     A common technical “buy” trigger is when price crosses above a short-term moving average (here, the 20‑day). This suggests:
     • Short-term momentum is turning positive.
     • Recent selling pressure is likely weakening and buyers are starting to take control. This directly aligns with the idea of a current buy signal, not something that occurred weeks ago.

3. Moving Average Relationship: PriceAboveMA200

   • Purpose: Ensure the broader, long‑term trend is upwards.
   • Rationale:
     Many traders only want to buy when the longer‑term trend is positive. Price above the 200‑day moving average:
     • Filters out names in primary downtrends where short‑term bounces are more likely to fail.
     • Aligns the short‑term buy signal (20‑day cross) with a bigger, structural uptrend — a classic “trade with the trend” approach. Together, the 20‑day cross and 200‑day filter find stocks where both short‑ and long‑term trends support a bullish case.

4. MACD: Bullish & Positive

   • Purpose: Confirm momentum and trend strength using a second, independent indicator.
   • Rationale:
     MACD turning bullish (MACD line crossing above its signal line) and being positive (above zero) is a widely used technical buy confirmation:
     • “Bullish” cross = momentum is shifting in favor of buyers.
     • “Positive” MACD = price is above its longer‑term average, reinforcing the uptrend signal. Using MACD in addition to moving averages filters out weaker setups where only one indicator is flashing “buy” while another remains neutral or bearish.

5. RSI Category: Moderate

   • Purpose: Avoid overbought conditions and extreme spikes that may be near exhaustion.
   • Rationale:
     A “moderate” RSI (typically around 40–60) aims to:
     • Exclude stocks that are already very overbought (e.g., RSI > 70), where a pullback is statistically more likely.
     • Avoid extremely oversold names where a bounce may be weak or part of a continuing downtrend. This seeks a balance: positive momentum (from MA and MACD) without chasing parabolic moves.

Why Results Match Your Request

• You asked for instruments with a buy signal. The screen combines multiple, commonly used technical buy criteria:
  • Price crossing above a short-term moving average (fresh trigger).
  • Price above the 200‑day MA (long‑term uptrend).
  • MACD bullish and positive (momentum confirmation).
• The liquidity filter ensures these signals come from tradable names, not illiquid outliers.
• The moderate RSI constraint aims to find setups where there is still reasonable upside potential rather than already overextended moves.

Overall, these filters are designed to identify stocks showing aligned, multi‑indicator bullish technical signals, which is a practical interpretation of “currently have a buy signal.”
