General Questions

Yes, ChuchoBot connects to Primary API via WebSocket and receives real-time instrument data during market hours.The application streams live market data including:
  • Real-time prices for monitored instruments
  • Bid/ask spreads
  • Market depth information
  • Order book updates
Data is updated continuously while the market is open and the WebSocket connection is active (green WiFi icon).
No, ChuchoBot does NOT send or execute any buy or sell orders to the market.The application is designed exclusively for:
  • Visualizing arbitrage opportunities in real-time
  • Analyzing settlement term spreads
  • Monitoring MEP and CCL dollar rates
  • Calculating potential profit/loss scenarios
All trading decisions and order execution must be done manually by the user through their broker’s platform.
No, ChuchoBot requires access to Primary API (Matriz) provided by your ALyC (broker).
The application cannot function without Primary API credentials and access.
To obtain Primary API access:
  1. Contact your broker (ALyC) to request access
  2. Verify your broker supports Matriz/Primary API integration
  3. Check the list of brokers offering DMA access
Popular brokers with Primary API support include:
  • Cocos Capital (requires Cocos Pro plan)

  • Veta Capital
  • Bull Market Brokers
  • Cohen

Configuration Questions

Some instruments use non-standard tickers for D (MEP dollar) and C (CCL dollar) instruments.Example: For treasury letter X20Y4, the D ticker is XY4D and C ticker is XY4C (not X20Y4D and X20Y4C).To configure exceptions:
  1. Go to menu Configuración > Excepciones de instrumentos $;D;C
  2. Enter the exception using the format: {Ticker $ Pesos};{Ticker D MEP};{Ticker C CCL}
  3. Separate each ticker with semicolons (;)
Example configuration:
X20Y4;XY4D;XY4C
This allows ChuchoBot to correctly identify and track D and C instruments that have irregular naming patterns.
To disable telemetry data collection in ChuchoBot:
  1. Close the application
  2. Open ChuchoBot.exe.config in a text editor
  3. Locate and delete the entire <connectionStrings>...</connectionStrings> section:
<connectionStrings>
  <add name="Primary.WinFormsApp.Properties.Settings.AppInsightsConnectionString"
    connectionString="..." />
</connectionStrings>
  1. Save the file
  2. Restart ChuchoBot
Removing the connection string will prevent the application from sending any telemetry data.
Use the same username and password that you use to access Matriz.ChuchoBot authenticates through Primary API using your existing Matriz credentials. There are no separate credentials to create or manage.
The Primary API Base URL depends on your ALyC (broker). Configure it in the Primary Login window.Common Primary API URLs:
  • Cocos Capital (requires Cocos Pro plan): https://api.cocos.xoms.com.ar
  • Eco Valores: https://api.eco.xoms.com.ar
  • Veta Capital: https://api.veta.xoms.com.ar
  • Bull Market Brokers: https://api.bull.xoms.com.ar
  • Cohen: https://api.cohen.xoms.com.ar
  • Adcap: https://api.adcap.xoms.com.ar
  • BCCH: https://api.bcch.xoms.com.ar
If your broker is not listed, contact them directly for the correct Primary API Base URL.

Technical Questions

Settlement term arbitrage involves exploiting price differences between the same instrument trading at different settlement periods (CI, 24hs, 48hs).Learn more:Example:
  • Buy NVDA at CI (immediate settlement) at $100
  • Sell NVDA at 24hs (next-day settlement) at $100.50
  • Profit from the settlement spread while managing collateral requirements
