Round Number Quarters Theory – FX Replay Guide

FX Replay does not offer a built-in Quarters Theory indicator, and the platform currently doesn’t support custom indicator uploads. However, you can still manually apply the Quarters Theory using FX Replay’s drawing tools and grid-based price awareness to structure your trades.

What is Quarters Theory?

Quarters Theory is a market structure concept where traders treat round numbers and their subdivisions (quarters) as key psychological levels — often acting as support, resistance, entry, exit, or reaction zones.

How to Use Quarters Theory in FX Replay

1. Manually Mark Round Numbers

• Identify the nearest major round number (e.g., 1.2000 on EUR/USD)
• Use FX Replay’s horizontal line tool to mark this level

2. Calculate and Plot Quarter Levels

• Add lines at 25%, 50%, and 75% distances from the round number
• Example:
  • If 1.2000 is your anchor, draw lines at:
    • 1.1975
    • 1.1950
    • 1.1925
• Duplicate and space out these lines to cover additional zones above and below

3. Use as Trade Framework

• Entry Zones: Watch for bounces or breaks at quarter levels
• Stop Loss & TP: Use quarter spacing to define risk/reward zones
• Reversals or Breakouts: Price often respects these levels intraday

4. Special Case – JPY Pairs

• JPY pairs use different decimals
• Use 25, 50, or 100 pip spacing instead of fractional decimals

5. Best Timeframe

• Use Quarters Theory on the 1H timeframe for day trading or scalping strategies inside FX Replay

Pro Tip

In FX Replay, you can create a “template” by drawing quarter levels around a key round number, then copy and slide them up/down to efficiently structure your entire chart. This simulates the effect of a Quarters Theory indicator — without needing automation.
