<p>The <b>Session Indicator</b> visually highlights the main global trading sessions — <b>Asian</b>, <b>London</b>, and <b>New York</b> — directly on the chart background. It helps traders quickly identify which session the current price action belongs to, improving contextual awareness during analysis.</p>
<p><b>Core Logic:</b></p>
<ul>
<li>The script divides the trading day into three distinct time windows corresponding to the major forex market sessions.</li>
<li>Each session’s start and end hours can be customized via <code>input.int()</code> controls.</li>
<li>The indicator calculates the current hour from the system timestamp and compares it against the defined session ranges.</li>
<li>When a bar falls within a session, a semi-transparent background color is applied to visually mark that region.</li>
</ul>
<p><b>Session Colors:</b></p>
<ul>
<li><span style="color:blue;">Blue:</span> Asian Session (Tokyo/Sydney)</li>
<li><span style="color:green;">Green:</span> London Session (European markets)</li>
<li><span style="color:red;">Red:</span> New York Session (U.S. markets)</li>
</ul>
<p><b>Usage:</b></p>
<ul>
<li>Helps identify which trading session is active and when liquidity or volatility is expected to rise.</li>
<li>Useful for day traders and scalpers to align their strategies with session-specific behaviors.</li>
<li>Can be combined with volatility indicators or volume analysis to spot overlaps and high-activity zones.</li>
</ul>
<p><b>Enhancements:</b></p>
<ul>
<li>Add background overlays for overlapping sessions (e.g., London–New York overlap) to identify high-volume periods.</li>
<li>Include optional session labels or text markers for clarity.</li>
<li>Integrate alerts when new sessions begin.</li>
</ul>
<p><b>Summary:</b></p>
<p>The Session Indicator is a simple but powerful visualization tool that helps traders synchronize their strategies with global market timings. By showing active sessions directly on the chart, it enhances situational awareness and decision-making precision.</p>
