MACD Crossover Screener

Fresh cross, existing state and zero-line filter

Use the same symbol, timeframe and MACD settings for both observations. In the rules below, current means the latest completed bar and previous means the completed bar immediately before it. Equality on the current bar is not a cross.

A two-bar example with different screening results

These are hypothetical raw MACD readings in price units, not market observations or a return forecast. Each row compares two completed daily bars using 12/26/9 EMA settings. Subtract signal from MACD to reproduce each histogram.

• The signal values are consistent with a 9-period EMA update: new signal = 0.2 x new MACD + 0.8 x previous signal.
• For example C, assume the current close is 50. The displayed MACD is 0.80% and signal is 0.64%. Their 0.16 percentage-point gap corresponds to the raw histogram of 0.08.
• Scaling both lines by the same positive denominator preserves their ordering. It does not make the raw histogram comparable across differently priced instruments. Missing values or a zero close cannot produce usable normalized lines.

What the Pineify MACD state actually means

Pineify combines histogram sign and direction in its MACD state. Bullish means the histogram is positive and higher than its previous value. Bearish means it is negative and lower than its previous value. Other combinations are neutral. A bullish label therefore includes some ongoing trends and is not a fresh-crossover flag.

• A histogram moving from +0.10 to +0.24 is bullish in this state model, even though it was already positive.
• A histogram moving from +0.24 to +0.08 remains above the signal line but is neutral in this state model because it is shrinking.
• The public payload provides the latest histogram, state and normalized lines. It does not provide a previous histogram or a crossing timestamp, so the table alone cannot establish a new crossover.

Confirm the daily close before counting a match

This public screener requests daily snapshots and caches each indicator response for up to four hours. It does not expose a separate confirmed-close flag for the daily calculation. A closed intraday source bar can still carry a higher-timeframe value that is changing, so treat an intraday daily reading as provisional.

• Select the intended market collection and check the exchange-qualified ticker. The available collections are a defined universe, not every listed instrument.
• Open that exact symbol in TradingView on a standard candlestick chart. Match the session and use close as the source with EMA lengths 12, 26 and 9.
• Wait for the symbol's daily session to end. Ignore the open candle and compare the two most recent completed daily bars. If the latest snapshot does not match them, exclude it from the confirmed shortlist.
• Record the market session, timezone, two bar dates, histogram values and confirmation time. A cache creation time or webhook receipt time is not the close time of every requested timeframe.
• If the value is missing, stale or rounded too close to zero to determine its sign, mark the result unverified. Do not treat a missing row as a negative signal.

Keep daily, hourly and weekly crosses separate

A daily MACD cross and an hourly MACD cross are different events because each EMA uses bars from its own timeframe. Twelve hourly bars are not twelve trading days. The public table is daily only; changing your TradingView chart interval does not change this table.

• For a daily trend filter with an hourly trigger, record the latest completed daily MACD state separately from the two completed hourly bars that establish the trigger.
• A daily cross can disappear before the daily close even after an hourly bar has closed. Weekly filters likewise need a completed weekly bar.
• Keep regular-session and extended-session settings consistent. Different sessions, data feeds or EMA warm-up history can produce different borderline crosses.

Use the snapshot to build a verifiable shortlist

Open Market Screener to organize your symbols and review its available indicator fields. For a custom rule such as a fresh cross above zero on a fixed list, describe the symbol list, timeframe, session and closed-bar requirement to Pine Script AI Coding Agent. Review its generated script on TradingView before relying on the results.

• A useful specification is: evaluate only completed daily bars; require current histogram > 0, previous histogram <= 0 and current MACD > 0; show the matching bar date and mark missing data separately.
• A custom multi-symbol Pine script is limited by TradingView request and execution limits. It is not an unrestricted exchange-wide scan.
• Keep entry, exit, sizing and costs separate from the screening rule. A candidate list is not evidence that the rule has a trading edge.
