Market Gate GO/NO-GO (Long Only)

This indicator is for traders who want a quick, objective answer to one question before they take any long: “Is the overall market environment supportive right now, or am I fighting the tape?” Most losses in long-only swing trading don’t come from picking the wrong stock — they come from buying good setups while the broader market is risk-off. This script is meant to solve that by acting as a top-level market regime gate you keep on your chart (or in a separate window) and check first. It does not place trades, does not connect to any broker, and it does not predict. It simply prints a daily GO / NO-GO state based on market conditions, and you use it as a permission layer before taking any long setups on individual tickers (breakouts, pullbacks, SMA crosses, reclaim/hold, etc.).

A simple indicator , mechanical risk filter designed to keep long entries aligned with broader market conditions. It does not place trades and does not connect to any broker. It prints a daily GO/NO-GO state and is meant to be used as a “permission layer” before taking any long setups on individual tickers.

Logic (Strict Market Gate)

Market Gate is GO only when all three conditions are true (daily data):

  • SPY is above its SMA(20)
  • QQQ is above its SMA(20)
  • VIX is below its SMA(10)

If any condition fails, Market Gate is NO-GO.

How to use

  • GO = you’re allowed to take long setups on your chart.
  • NO-GO = stand down (avoid new longs, avoid “catching falling knives”).
  • Combine with your own entry trigger (e.g., SMA10 crossing above SMA20, reclaim/hold, breakouts).
  • Works on any chart timeframe, but the gate itself always uses daily SPY/QQQ/VIX.

Signals / Visuals

  • GO/NO markers are printed once per day (first bar of the day on intraday charts) to avoid label spam.
  • Optional SMA10/20 plots can be used for your local entry timing.

Inputs

  • Symbols: SPY, QQQ, CBOE:VIX (editable)
  • Lengths: SPY/QQQ SMA length (default 20), VIX SMA length (default 10)
  • Optional: require both SPY & QQQ above SMA (strict) vs either (looser)

Notes

This is a market-regime filter, not a full strategy. It will intentionally stay NO-GO during downtrends and volatility expansions. Always test and adjust to your own risk tolerance and instruments.
