RSI stands for Relative Strength Index. It's a momentum oscillator that measures how fast and how much a price has moved over a recent period — and whether that move is stretched too far in one direction.

RSI runs on a 0–100 scale. A reading below 30 means the asset has been selling off hard and may be oversold — due for a bounce. Above 70 means it's been running up and may be overbought — due for a pullback.

ScalpClock uses a 14-period RSI with Wilder smoothing on 5-minute bars — the same methodology professional traders use. That means we look at the last 14 candles (70 minutes of price action) and compute whether the current move is extreme relative to recent history.

Most signals are soft — a single indicator nudging in one direction. A HARD signal is different. It means multiple independent indicators are all pointing the same way at the same time. That's confluence, and confluence is where edge lives.

A HARD call signal fires when all of these are true simultaneously:

The same logic applies in reverse for puts: RSI ≥ 70, price above VWAP, volume surging — those three together earn a HARD put signal.

VWAP stands for Volume-Weighted Average Price. It's the average price a stock has traded at throughout the day, weighted by how much volume occurred at each price level. Institutional traders — funds, desks, algorithms — use it as their primary intraday benchmark.

Because institutions use VWAP to decide whether they're getting a good fill or a bad one, price tends to mean-revert to it throughout the day. That makes it a powerful anchor for timing entries.

ScalpClock calculates VWAP fresh each day from the open using today's 5-minute bars, so you always see the current session's anchor — not yesterday's stale level.

When RSI is oversold and price is below VWAP, that's two independent signals agreeing. That combination is the engine behind most HARD call signals on ScalpClock.

Every ticker ScalpClock tracks gets a confluence score from 0–100. The score combines how extreme the RSI reading is, whether price is on the right side of VWAP, and whether volume is surging. The score drives which priority tier a signal falls into.

The AI ranks all 20 tickers by score and surfaces the top 10 opportunities each refresh cycle. No Trade signals don't make the board unless fewer than 10 others qualify.

ScalpClock tells you when to enter. Options give you leverage to profit from that timing without holding the underlying stock. Here's the minimum you need to understand.

0DTE options (zero days to expiration) are popular with scalpers because they move fast and require less capital. But they lose value every minute — time decay (theta) is brutal. A signal needs to play out quickly on 0DTE, typically within the same session.

For scalping, most traders look for options that are at-the-money (ATM) or one strike in-the-money (ITM). These have the best balance of leverage and delta — meaning they move closely with the underlying stock price.

ScalpClock is the timing layer — it tells you when the technical conditions favor a move. The rest — expiry, strike, position size, stop-loss — is your job as the trader. Use the Exit Assistant to know when to close.
