A row is a candidate, not a trade
Green Horizon scanners filter the market and show why a symbol was listed. A row is not a buy signal, a sell signal, or an instruction to enter. PreMarket Scanner and News Scanner are included with Premium. Momentum Scanner and Market Replay are separate subscriptions. Trading Coach is a membership-checked desktop connection, not one of these intraday boards.
The boards themselves require access. This page describes the rules in the application. It does not show live prices, and the examples below are hypothetical.
Pre-market price and volume
The PreMarket Scanner runs on weekdays from 4:00 to 9:30 AM Eastern. After 9:30 it keeps that session’s final list on screen until the next session. It ranks gap-up movers and shows volume, float, distance from VWAP, news, and a Ramp score.
Gap percent during premarket compares the last price with the previous close. Relative volume on this board is today’s volume divided by all of the previous session’s volume. It is not an average of many days. A quiet previous day makes the ratio look large even when today’s share count is modest.
Float rotation is today’s volume divided by float. When free float is missing, the float column uses shares outstanding and marks it with a tilde. That substitution is a data gap, not a tighter float.
The Ramp score
Each PreMarket row has ten checks. 8 or more is labeled Tradeable, 6 or 7 is labeled Watch, and anything lower is labeled Avoid. Those words are checklist labels. They are not orders.
Volume passes when premarket volume is at least 500,000 shares, or volume on the day is at least 1,000,000 shares, or relative volume is at least 2 times the previous session. One of those three is enough for that single check.
VWAP percent is (last price − VWAP) / VWAP. The VWAP check passes at -1% or higher, which includes price up to 1% under VWAP. The timing check fails when that same percent is above 20. A stock can be “through VWAP” and still be too far extended for the timing check.
The daily-chart check fails when price is 12% or farther below the high of day. The risk check asks whether the low of day is close enough to define a stop: the distance from the low to the last price, divided by the last price, has to be 12% or less. The reward check wants at least 3% of room up to the high, unless price is already through that high. The scanner does not place the stop or the target.
Prior runner does not pass from the feed. The note on that check tells you to look at the one-year chart yourself. A score of 10 is not available from the data alone. Catalyst passes only for a company headline. A generic market roundup does not count.
The entry-pattern check passes when price is at or above VWAP and the 9-period EMA is within 1% under price, or when price is just under VWAP in an uptrend, or when an uptrend is still near the high of day. A gain of at least 10% with the volume check passing can also light that check. If none of those relationships match, the label is “Watch only” and the check fails. A label on this check is not an entry recipe, and this page does not teach the Premium strategies those labels refer to.
Hypothetical PreMarket row
This row is invented so the arithmetic can be checked. It is not a print from a trading session, and it is not a result the scanner produced.
Last price $4.00. VWAP $3.90. VWAP percent is (4.00 − 3.90) / 3.90, about 2.6% above VWAP, so the VWAP check passes and the timing check passes. The 9-period EMA is $3.95, so price is above that average and the entry-pattern label is “VWAP / EMA9 hold.” High of day $4.10. Room to that high is (4.10 − 4.00) / 4.00 = 2.5%, which is under 3%, so the reward check fails. Low of day $3.80. The distance from that low is 5% of the last price, so the risk check passes. Premarket volume is 800,000 shares, so the volume check passes. A company headline is present, so catalyst passes. The trend is up, so the clean-chart check passes. Price is about 2.4% under the high, so the daily-chart check passes.
That is eight passing checks. Prior runner stays unchecked. Reward stays unchecked. Eight is the Tradeable label. The label does not mean every check passed, and it does not mean the one-year chart has been reviewed.
News and catalysts
The News Scanner lists movers that have a company headline. Market-roundup headlines are left off the board. On the PreMarket Ramp score, the same kind of roundup does not pass the catalyst check.
A headline explains attention. It does not tell you the direction. The scanner does not grade whether the story is good for the company. Headlines older than about 72 hours are left out. “Holding” means the last price is at least $0.30 above the price stored when that headline was first seen, and the day is up. Good and bad marks are notes in that browser only. They are not part of the score.
Opening range, VWAP, and EMA9
The Momentum Scanner builds its list from the day’s top gainers and compares the last price with three references. It runs on weekdays from 4:00 AM to 8:00 PM Eastern. Outside that window it can show the last list from the session. It does not keep fetching.
The opening-range high is the highest price from 9:30 to 9:45 AM Eastern. Before 9:45 that condition does not match anything. After 9:45 it matches when the last price is within 1% of that high, measured as the absolute distance divided by the high, or when the last price has traded above the high.
The premarket high is the highest price from 4:00 to 9:30 AM Eastern. The condition matches when the last price is within 2.5% of that high, above or below it, using the same absolute-distance formula.
The EMA comparison uses the 9-period EMA of 1-minute closes against VWAP. An up cross is an EMA that was at or below VWAP on the previous bar and is above VWAP on the later bar, with that bar’s close still at or above VWAP. A down cross is the mirror. An older cross, up to 400 bars back, counts only while the last price is still on that side of the current VWAP. The pullback case is separate: the last price is within 0.5% of VWAP, and that percent uses the last price as the denominator, not VWAP.
The EMA/VWAP case also requires a last price from $0.30 to $15.00, at least 60,000 shares on the latest bar, and at least 88,000 shares on the day. A stock can match the opening range and still fail this case.
Hypothetical Momentum row
This second example is also hypothetical. The prices were chosen to show two conditions that disagree.
It is after 9:45 AM Eastern. The 9:30–9:45 high is $4.00. The last price is $3.97. The absolute distance is 0.75% of that high, which is inside the 1% band, so the opening-range condition can match. The premarket high is $4.20. The same last price is about 5.5% away from that high, which is outside the 2.5% band, so the premarket condition does not match. If the 9-period EMA has crossed above VWAP inside the lookback and the last price is still at or above VWAP, the cross can match as well. Matching one condition is enough to be listed. The row should show which conditions matched. None of them is an entry.
Where the reading fails
Data can be delayed or incomplete. The scanner status line is the place to see when the last successful update arrived. A symbol can appear before its levels have finished calculating.
Relative volume against one previous day, a float built from shares outstanding, and a headline that is merely recent are all ways a row can look cleaner than the chart. A price within 1% of the opening-range high can be falling back into the range. The Momentum Scanner does not require the break to hold.
The risk check on the Ramp score only says whether the low of day is close enough to write a stop against. If that low is wide, or missing, the check fails and you still do not have a stop. Invalidation is your rule for when the idea is wrong. The scanner does not calculate it for you.
Market Replay is practice on past weekdays using 1-minute bars and a paper account that starts at $10,000. Orders are not sent to a brokerage. A paper result is not a track record.
Trading Coach daily labels, including a completed day versus a day that is still in progress, are a different product. They are not created by these intraday boards, and a premarket print does not finish a daily bar.
