Here are the Professional versions for both MetaTrader 4 and MetaTrader 5.

These versions introduce the Equilibrium Midline (50%), Liquidity Projection Lines that extend into the London session, a Heads-Up Display (HUD) anchored to the chart corner, and Real-time Push Alerts that trigger the moment the expansion threshold is crossed.

Save this as AsianMicrostructure_PRO.cs in your cTrader Automate indicators folder.

This Pro version leverages cTrader's native UI capabilities to create a sleek, modern HUD dashboard that anchors to the chart window and updates without lagging. It uses native DateTime charting methods to effortlessly project liquidity lines into the future London session, bypassing the bar-index limitations found in other platforms.

To make this the ultimate, elite-tier microstructure tool for your M15 charts, we need to move beyond just measuring the range and start automatically mapping how London interacts with that range.

Since your strategy revolves around liquidity and mean-reversion versus expansion, this [ELITE] upgrade introduces three advanced smart-money concepts:

Automated Liquidity Purge Detection (BSL/SSL): It actively monitors the London projection window. If price sweeps the Asian High (Buy-Side Liquidity) or Asian Low (Sell-Side Liquidity), it automatically tags the chart with a "BSL/SSL Purge" marker and fires an alert.

Deep Premium & Discount Quartiles (75% & 25%): Equilibrium (50%) is great, but the highest probability mean-reversion entries occur in the outer quartiles. The script now draws the 75% (Premium) and 25% (Discount) internal thresholds.

Forward-Projected PD Arrays: Instead of just drawing dotted lines, it projects a lightly shaded Premium Zone (Red) and Discount Zone (Blue) into the London session, giving you a crystal-clear visual of where you are in the intraday matrix.

How this alters your London Playbook:

The Expansion Override: If the box turns RED during Tokyo, the rest of the indicator is purely informational. The mean-reversion playbook is closed.

The High-Probability Fade: If the box stays BLUE (Normal), and London pushes up into the Red Shaded Premium Zone without immediately breaking the High, you look for your M1/M5 short setups at the 75% Quartile.

The Judas Swing / Turtle Soup: If the box is BLUE, and London aggressively spikes through the solid Red boundary line (Asian High) and immediately rejects back inside the zone, the script instantly prints a BSL tag. That is your mechanical confirmation that liquidity was purged, not expanded upon. You enter the fade targeting the Equilibrium (50%) or the 25% Quartile.

Here are the Elite-tier versions for MetaTrader 4 and MetaTrader 5.

These scripts upgrade the previous versions with full Smart Money Concepts (SMC) integration: they project Premium/Discount arrays into the London session, track the 25%/75% internal quartiles, mechanically detect BSL (Buy-Side) and SSL (Sell-Side) liquidity purges, and dynamically update the HUD.
