A method to update the latest item

[moshtaghi]

I need a method to update the latest candle data to calculate current candle indicators. I forked the project and add this feature (it's very buggy).

Please let me know if this feature is needed. I'll get it completed

for example in SMA:

// THIS IS FOR ADD NEW CANDLE DATA
  override update(price: BigSource): Big | void {
    this.prices.push(price);

    if (this.prices.length > this.interval) {
      this.prices.shift();
    }

    if (this.prices.length === this.interval) {
      return this.setResult(SMA.getResultFromBatch(this.prices));
    }
  }

// THIS IS FOR UPDATE THE LATEST CANDLE DATA
  override updateLatestCandle(price: BigSource): void | Big {
    this.prices[this.prices.length - 1] = price;

    if (this.prices.length < this.interval) {
      throw new NotEnoughDataError();
    }

    if (this.prices.length === this.interval) {
      return this.setResult(SMA.getResultFromBatch(this.prices));
    }
  }

Hi moshtaghi, what's the use case here? Why do you want to modify an existing candle?

Hi benny, I need to calculate the current (open) candle indicators. Since the OHCL is updated every second, I cannot use the update method.

Hi @moshtaghi, your feature request is now implemented. In trading-signals v6 you can use a replace method to update the current price. 🥳
