Momentum Scalping Strategy

A short-term trading strategy that rides existing momentum with tight risk controls.

Use search_sdk then execute_code. Do not call retired MCP tool names (get_tickers, place_order, …).

Entry Criteria

Step 1: Scan for Momentum

const tickers = await eterna.getTickers();
const longs = tickers.filter((t) => parseFloat(t.price24hPcnt) > 0.003);
const shorts = tickers.filter((t) => parseFloat(t.price24hPcnt) < -0.003);
return { longs: longs.slice(0, 10), shorts: shorts.slice(0, 10) };

• Long candidates: price24hPcnt > +0.003 (+0.3% in 24h)
• Short candidates: price24hPcnt < -0.003 (-0.3% in 24h)

Step 2: Confirm with Orderbook

const book = await eterna.getOrderbook(symbol, 50);
const bidVol = book.bids.reduce((s, [, q]) => s + parseFloat(q), 0);
const askVol = book.asks.reduce((s, [, q]) => s + parseFloat(q), 0);
return { bidVol, askVol, longOk: bidVol >= 1.1 * askVol, shortOk: askVol >= 1.1 * bidVol };

• Long confirmation: bid volume >= 1.1 × ask volume
• Short confirmation: ask volume >= 1.1 × bid volume

Step 3: Check Position Limits

const positions = await eterna.getPositions();
return {
  count: positions.length,
  hasSymbol: positions.some((p) => p.symbol === symbol),
};

• Do NOT enter if already holding this symbol (max 1 per symbol)
• Do NOT enter if total open positions >= 4

Exit Rules

Set these on every eterna.placeOrder call:

Parameter	Value
takeProfit	1.0% from entry price
stopLoss	0.6% from entry price
Leverage	<= 5x via eterna.setLeverage

Example entry

await eterna.setLeverage(symbol, "3");
const order = await eterna.placeOrder({
  symbol,
  side: "Buy", // or "Sell"
  orderType: "Market",
  qty,
  takeProfit,
  stopLoss,
});
return order;

Cycle workflow

Prefer one execute_code call per cycle: scan → confirm → size → place (or skip) → return a structured summary.
