Fixed Time Window High & Low

Unlock the power of trading the first hour’s price action with this dynamic indicator by Ats9 that automatically plots the High and Low of any fixed time window you choose—typically the crucial first 60 minutes after the market opens.

What It Does:

Calculates and draws clean, bold horizontal lines representing the session high and low during your specified time range

Extends these lines well beyond the session, so you always have clear breakout and support/resistance levels visible throughout the day

Fully customizable session times, colors, and labels to fit your trading style

Developed by ATS9, designed for traders who value precision and clarity in breakout levels

Why It Works:
The initial fixed time window often represents where major players establish their early bias. Breakouts above or below these levels often lead to strong momentum moves, giving you a defined edge to catch the market’s direction early.

How I Trade It:

Observe the first hour: Let the market build its initial range

Wait for decisive breakout: When price breaks above the session high or below the session low, enter in the breakout direction

Ride momentum: Hold the trade throughout the day, using the extended lines as reference points for support, resistance, and exits

Trade both sides: Be ready to go long or short depending on which level breaks first

This approach harnesses intraday volatility and institutional activity to keep you in the flow of the market — perfect for day traders seeking clear, actionable signals with minimal guesswork.
