MidaTradingSystem()

Trading systems, trading bots or expert advisors are represented by the MidaTradingSystem class.

The first step to create a trading system is extending the MidaTradingSystem class.

• Example 1

import { MidaTradingSystem, } from "@reiryoku/mida";

export class SuperTradingSystem extends MidaTradingSystem {
    async configure () {
        // Called once per instance before the first startup
        // can be used as async constructor
    }
    
    async onStart () {
        // Called when the trading system starts being operative
    }
    
    async onStop () {
        // Called when the trading system stops being operative
    }
}

TIP

A trading system has an integrated market watcher, the watched() method is used to configure the market watcher before the first startup of the trading system

• Example 2

import { MidaTradingSystem, MidaTimeframe, } from "@reiryoku/mida";

export class SuperTradingSystem extends MidaTradingSystem {
    watched () {
        return {
            "BTCUSD": {
                watchTicks: true,
                watchPeriods: true,
                timeframes: [ MidaTimeframe.H1, MidaTimeframe.D1, ],
            },
        };
    }
    
    async configure () {
        // Called once per instance before the first startup
        // can be used as async constructor
    }
    
    async onTick (tick) {
        const { bid, ask, date, } = tick;
    }
    
    async onPeriodClose (period) {
        const [ open, high, low, close, ] = period.ohlc;
        
        switch (period.timeframe) {
            case MidaTimeframe.H1: {
                // Closed H1 candlestick
                
                break;
            }
            case MidaTimeframe.D1: {
                // Closed D1 candlestick
                
                break;
            }
        }
    }
}
