Keep track of both the daily and weekly candles? - boba - 07-01-2019
I am trying to keep track of the daily and the weekly candles. I set the default candle to the daily.
I am attempting to use CandleBatcher, but when I log out the candles for both the daily and the weekly, I noticed the order is strange. For example, if I just wanted to keep track of the weekly price and price of the previous day, the daily candles sort of "get ahead" of the weekly candles and it's inconsistent.
I am sure I am just doing something wrong, but if not I am thinking of a better way to store them. Perhaps store a map of the last 30 days where: date => { dailyCandle, weeklyCandle } or something.
Code:
strat.init = function () {
this.batcherWeekly = new CandleBatcher(7);
this.batcherWeekly.on('candle', this.update1Week);
}
strat.update = function (candle) {
console.log('D', candle);
this.lastDailyPrice = candle.close;
this.batcherWeekly.write([candle]);
this.batcherWeekly.flush();
}
strat.update1Week = function (candle) {
console.log('W', candle);
// if I'm on week that ends on Jan 7, it's unclear how to get the previous day Jan 6 price because it's not this.lastDailyPrice
}
