package org.cryptocoinpartners.schema;

import org.joda.time.format.DateTimeFormat;
import org.joda.time.format.DateTimeFormatter;

public class Bar extends Event {
	private long timestamp;//時間戳
	private Double open;//開盤價
	private Double close;//收盤價
	private Double high;//最高價
	private Double low;//最低價
	private Market market;//市場
	private static final DateTimeFormatter FORMAT = DateTimeFormat.forPattern("yyyy-MM-dd HH:mm:ss");

	// private static final SimpleDateFormat FORMAT = new SimpleDateFormat("dd.MM.yyyy kk:mm:ss");
	private static final String SEPARATOR = ",";

	public Bar(long timestamp, Double open, Double close, Double high, Double low, Market market) {
		this.timestamp = timestamp;
		this.open = open;
		this.close = close;
		this.high = high;
		this.low = low;
		this.market = market;
	}

	@Override
	public long getTimestamp() {
		return timestamp;
	}

	public Double getOpen() {
		return open;
	}

	public Double getClose() {
		return close;
	}

	public Double getHigh() {
		return high;
	}

	public Double getLow() {
		return low;
	}

	public Market getMarket() {
		return market;
	}

	protected void setTimestamp(long timestamp) {
		this.timestamp = timestamp;
	}

	protected void setOpen(Double open) {
		this.open = open;
	}

	protected void setHigh(Double high) {
		this.high = high;
	}

	protected void setLow(Double low) {
		this.low = low;
	}

	protected void setClose(Double close) {
		this.close = close;
	}

	protected void setMarket(Market market) {
		this.market = market;
	}

	@Override
	public String toString() {

		return "Bar Start=" + (getTimestamp() != 0 ? (FORMAT.print(getTimestamp())) : "") + SEPARATOR + "Market=" + getMarket() + SEPARATOR + "Open="
				+ getOpen() + SEPARATOR + "High=" + getHigh() + SEPARATOR + "Low=" + getLow() + SEPARATOR + "Close=" + getClose();
	}
}

這個Bar就是條。就是我們K線圖中的一根K線。它包含時間以及該時間點上的OCHL值。

這裏有個Market，我們在後面的節中會說明。

我們的每一節都很簡單，但就是一節節簡單的內容最後走下來就組成了一個複雜的量化交易平臺。

路遙知馬力。
