📊 The 8 automatically detected signals

Breakout signals

• ORB (Opening Range Breakout): break of the high or low of the first 5, 15 or 30 minutes of the session
• BHOD / BLOD (Break High / Low Of Day): break of the day's high or low, confirmed by a margin (0.25% by default), from 10:29 AM
• Key levels (PMH / PML, PDH / PDL, PWH / PWL): break, up or down, of the pre-market, previous-day and previous-week high or low (your choice)
• Volume Breakout: one-minute volume above 4 times the average of the last 20 minutes

Momentum signals

• Turbo Break (Up / Down): sharp price acceleration within one minute (±0.75% by default, from 10:29 AM)
• Extreme Reversal: V-shaped reversal, a fast drop or rise followed by a clear recovery in the other direction (by default: 1.5% within 10 minutes, then a retrace of half the move, from 10:29 AM)

Technical signal

• VWAP: the price moves away from the VWAP (volume-weighted average price) beyond an adjustable threshold (±1% by default)

Relative volume signal: time-of-day RVOL (Ultimate plan and Discovery trial)

• Relative volume: the volume traded since the open, compared with the stock's usual volume at the same time of day (median of the last 20 sessions). 2× = twice as active as usual
• Shown from 9:45 AM in the alert tables, the monitored tickers list and the CSV export
• Alert when your thresholds are crossed (2× and 3× by default), once per threshold per session
• Breakout filter: show ORB, BHOD / BLOD and key level alerts only on truly active stocks

All signals are calculated on closed one-minute candles during the regular session (9:30 AM – 4:00 PM New York time). Some need a few minutes of trading before they are fully active.

❓ Frequently Asked Questions

What is AlerTrade?

AlerTrade is a day trading alert service: it detects technical setups in real time (ORB, VWAP, high of day, volume…) on U.S. stocks.

Which markets and hours are covered?

U.S. stocks listed on the NYSE and NASDAQ, during the regular session: 9:30 AM to 4:00 PM New York time.

What is the ORB (Opening Range Breakout) strategy?

ORB detects a break of the high or low of the first 5, 15 or 30 minutes of the session, a key strategy for capturing morning volatility.

How does the VWAP alert work?

It alerts you when the price moves away from the VWAP (volume-weighted average price) beyond an adjustable threshold (±1% by default). A neutral zone prevents repeated alerts while the price stays close to the VWAP.

Does the system detect unusual volume?

Yes. The Volume Breakout alert flags volume above 4 times the average of the last 20 minutes (adjustable threshold), often a sign of a significant move. With the Ultimate plan and the Discovery trial, time-of-day RVOL also compares the volume traded since the open with the usual volume at the same time of day: 2× means twice as active as usual.

What is a “Turbo Break” signal?

A Turbo Break flags a sharp price acceleration within a one-minute candle (±1% by default), useful for scalping and momentum trading.

Which setting style should I choose?

AlerTrade offers three ready-made styles, measured over a year of replayed sessions: Reactive (about 6 alerts per ticker per session, from 9:59 AM, more opportunities but more noise), Balanced (default, about 3 alerts per ticker, the best trade-off) and Selective (1 to 2 alerts per ticker, only the strongest moves). Reactive suits following a few tickers closely, Balanced a list of 20 to 50 tickers, Selective a long list. You can start from a style and save your own variant. These are past statistics, with no promise of gains.

Can I test my settings before trading?

Yes, with the Premium and Ultimate plans, and during the free Discovery trial: Backtest mode replays past sessions (up to 30 days back with Ultimate, 6 days with Premium and the trial), up to 4, 9 or 15 times faster depending on the plan, so you can validate your settings.

Can I monitor my own list of stocks?

Yes, with the Premium and Ultimate plans: pick a predefined list (Nasdaq 50, S&P 50, Dow Jones 30, Magnificent 7, thematic lists…) or upload your own list as a CSV file. The Discovery plan monitors a fixed list of 10 large-cap stocks.

Are the alerts instant?

Alerts are calculated on closed one-minute candles, which avoids false signals mid-minute. How often the analysis runs depends on your plan: every 60 seconds (Discovery), as fast as 30 seconds (Premium) or 10 seconds (Ultimate).

Do you offer sound alerts?

Yes. A customizable sound alert (sound of your choice) can be turned on for each type of signal.

Can I try AlerTrade for free?

Yes. The Discovery plan is free for 7 days, with no credit card required. Your access starts as soon as you sign up. See plans

Does AlerTrade place trades for me?

No. AlerTrade alerts you, you decide. You trade with the broker of your choice: no brokerage account is connected to AlerTrade.

How does payment work for the Premium or Ultimate plan?

After you sign up, we email you the invoice for your plan. It is activated as soon as we receive your payment; in the meantime, you enjoy the Discovery plan.

Which devices can I use AlerTrade on?
