Handlers are the backbone of your trading strategy. They respond to specific events, like price updates or position changes, and help you automate your trading decisions. In this guide, we’ll break down each handler in detail, explain how to build the State and Update portions, and provide three examples for each handler to show how they can be used in different trading strategies.
| Handler | When It Runs | Example Use Case |
|---|---|---|
| On Price Update | New price update (candle or trade) | Check if the price reaches a certain level. |
| On Update | Periodically (e.g., every few seconds) | Monitor open positions or update indicators. |
| On Update Long | Long position (buy trade) is updated | Adjust stop-loss or take profit for buy trades. |
| On Update Short | Short position (sell trade) is updated | Adjust stop-loss or take profit for sell trades. |
| On Update Closing | Position is being closed | Log final profit or loss before closing. |
| On Position Open | New position is opened | Log entry price or set up stop-loss. |
| On Position Update | Open position is updated | Monitor and manage open trades. |
| On Position Close | Position is closed | Calculate and log profit or loss. |
