This guide will help you understand how the Strategy Editor works in Buddy Trading. Think of it as a tool that lets you create automated trading strategies without needing to write complex code. Here’s a breakdown of how it works:

1. What Are Handlers?

Handlers are like "event listeners" that respond to specific moments in your trading strategy. For example, when a new price update happens or when a trade position is opened or closed. Here’s a list of the main handlers:

• on_price_update: Runs when there’s a new price update (like a new candle or trade).
• on_update: Runs periodically to check on your strategy.
• on_update_long: Runs when a long position (buying) is updated.
• on_update_short: Runs when a short position (selling) is updated.
• on_position_open: Runs when a new trade position is opened.
• on_position_close: Runs when a trade position is closed.

Each handler is like a small program that decides what to do when something happens in the market.

2. How Do Handlers Work?

Every handler receives two pieces of information:

1. State: This is like a memory box that stores all the important details about your strategy, such as open trades, historical data, and custom settings.
2. Update: This is the new information coming in, like the latest price or candle data.

Here’s an example of what happens inside a handler:

async (state = {}, update = {}) => {
  const { mts, price, candle } = update; // Get the latest data
  return state; // Update the state if needed
}

• mts: The timestamp of the update.
