Stockbit BID Size Alarm (ARA/ARB Mode)

This script is designed to monitor BID activity for stocks on Stockbit, especially for the Indonesia Stock Exchange (IDX). It’s tailored for two critical trading conditions:

1. ARA Mode (Auto Reject Atas)

  • Purpose: Detect when a stock that has reached its upper limit price (ARA) starts to weaken.
  • Mechanism: You input a threshold lot size (e.g., 10 lots). If the top BID volume drops below this value, the script triggers an audible alarm, signaling that the strong demand may be fading.

2. ARB Mode (Auto Reject Bawah)

  • Purpose: Detect when a stock that is stuck at its lowest price (ARB) shows signs of recovery.
  • Mechanism: You input 0 as the threshold. As long as there’s no BID activity, the stock is assumed to be stuck. If any BID message appears, it triggers the alarm, signaling potential end of ARB.

🔧 Technical Features

  • Hooks into the Stockbit WebSocket to intercept real-time trading messages.
  • Filters and parses only the |BID| data for a specific stock symbol (e.g., “BBCA”).
  • Converts BID volume from raw units to lot size (1 lot = 100 shares).
  • Displays current status with timestamp, mode, and BID ratio next to the order book.
  • Plays an alert sound when conditions are met.
