Scalp pit — 5m and 15m Up/Down grid
The six-market scalping grid: what it shows, how to read the technical gauges, and how one-tap FOK works.

What it is
A dense 6-market grid for BTC / ETH / BNB / SOL / XRP / DOGE "Up or Down" 5-minute and 15-minute Polymarket windows. Every row has a live WebSocket top-of-book, one-tap $1 / $5 / $10 FOK buttons for both UP and DOWN sides, a limit-order pad, and a technical-signal strip.
How to read the gauges
- RSI-14 — Wilder-smoothed, 0-100. Green zone (< 30) means oversold: mean-reversion long setup. Red zone (> 70) means overbought.
- Momentum — composite score in [-3, +3] aggregated from RSI zone, EMA9/21 cross, last 3-candle direction, volume spike.
- σ — std-dev of last 12 closes as % of spot. Below 0.15% = SQUEEZE (contraction, expect breakout).
- EMA↑ / EMA↓ — is EMA9 above EMA21 on the current timeframe?
- VOL↑ — did the last closed candle print > 1.5× recent volume?
- Support / Resistance — min low / max high of last 12 candle wicks, with distance-from-spot in %.
Order sizing (why FOK ceils to $1)
Polymarket enforces a $1 minimum notional per order. When the ask is 64¢, a naive round-down "1 / 0.64 = 1.56 shares" would cost $0.998 — rejected. We ceil to 2 shares ($1.28 notional) so the order actually makes it through. For $5 and $10 tiles we still use rounding — the surface just displays the actual cost.
TP/SL for open positions
Every position row exposes TP (Take Profit) and SL (Stop Loss) inputs. Enter a cent price and hit Arm. TP places a GTC SELL at that price. SL runs in your browser and fires a market close when the ask crosses your threshold.
The risk gate applies
Rolling 24h BUY cap from Settings. TP/SL / manual close are never blocked (they reduce risk).
