币安期货多币种对冲策略最近的复盘和分钟级K线回测的结果
币安多币种对冲策略的研究报告已经发了3篇，这里是第4篇。前三篇的连接，没看的一定要再看一遍，可以了解策略的成型思路，具体参数的设置和策略逻辑。

很多人还不会使用研究环境，这里有一篇简单的入门介绍:https://www.fmz.com/bbs-topic/4388
本篇文章要复盘以下最近1周的实盘情况，总结一下得失。由于爬取了最近两个月的币安期货分钟线数据，可以更新下原来1hK线的回测结果，更能说明一些参数设置的含义。

分钟线数据
数据从2月21日到4月15下午两点，共77160*24条，这大大降低了我们的回测速度，回测引擎也不够高效，可以自行优化。以后有需要，我会定期追踪一下最新数据。

过去一周复盘
策略代码4月10号在微信群放出，刚开始就有一批人跑起了策略2——做空超涨做多超跌，开始的三天，收益很好，回撤很低，迅速激发了大家的热情。部分人放大了杠杆，甚至是满杠杆操作，收益一天就干到了10%。策略广场也公开了大量的实盘，很多人开始不满足与保守的推荐参数，纷纷放大了交易量。4月13后但由于BNB的独立行情，策略开始回撤和横盘，如果按默认3%的trade_value来看，大概回撤了1%。但很多人由于放大的参数，导致赚的少，亏得多。这一波回撤还算及时，让大家冷静了一些。

首先看一下策略二的全币种回测，这里由于是分钟更新，Alpha参数需要调整。从实盘来看，曲线走势相符，说明我们的回测可以作为很强的参考，净值从4.13日到达净值顶点一直处于回撤和横盘阶段。

策略2做多超跌做空超涨盈利分析
把最后账户信息打印出来，可见大部分币种都带来了利润，BNB亏损最多，这也是主要因为BNB走出了一波独立行情，上涨不少,最大偏离了0.06。

最近两天流行跑主流币策略，我们也回测一下这种策略。由于币种减少，trade_value适当增加4倍以对比,结果表现不错，尤其是最近回撤很小。
需要注意的是只跑主流币在更长时间的回测中是不如全币种的，回撤也更多。自己可以动手在小时线上回测以下，主要是因为币种少了资金分散，波动性反而上升。

Alpha = 0.001
price_usdt_btc_norm2 = price_usdt_btc/price_usdt_btc.ewm(alpha=Alpha).mean() #这里和策略一致，用了EMA
trade_symbols = ['ETH','LTC','EOS','XRP','BCH']
price_usdt_btc_norm_mean = price_usdt_btc_norm2[trade_symbols].mean(axis=1)
e = Exchange(trade_symbols,initial_balance=10000,commission=0.00075,log=False)
trade_value = 1200
for row in price_usdt.iloc[-7500:].iterrows():
    e.Update(row[0], row[1])
    for symbol in trade_symbols:
        price = row[1][symbol]
        if np.isnan(price):
            continue
        diff = price_usdt_btc_norm2.loc[row[0],symbol] - price_usdt_btc_norm_mean[row[0]]
        aim_value = -trade_value*round(diff/0.01,1)
        now_value = e.account[symbol]['value']*np.sign(e.account[symbol]['amount'])
        if aim_value - now_value > 0.5*trade_value:
            e.Buy(symbol, price, round((aim_value - now_value)/price, 6),round(e.account[symbol]['realised_profit']+e.account[symbol]['unrealised_profit'],2))
        if aim_value - now_value < -0.5*trade_value:
            e.Sell(symbol, price, -round((aim_value - now_value)/price, 6),round(e.account[symbol]['realised_profit']+e.account[symbol]['unrealised_profit'],2))
stragey_2c = e

(stragey_2c.df['total']/e.initial_balance).plot(figsize=(17,6),grid = True);

手续费和策略参数分析
由于前几个报告用的都是小时线，和实盘参数情况参数很大，现在有了分钟线，就可以看出来一些参数要如何设置，首先先看默认参数的设置:

Alpha = 0.03 指数移动平局的Alpha参数，设置的越大，基准价格跟踪越敏感，交易的越少，最终持仓也会越低，降低了杠杆，但会降低收益，降低最大回撤。
Update_base_price_time_interval = 30*60 多久更新一次基准价格, 单位秒，和Alpha参数相关,Alpha 设置的越小，这个间隔也可以设置的更小
Trade_value：山寨币价格（BTC计价）每偏离指数1%持有价值，需要根据自己投入的总资金和风险偏好决定，建议设置为总资金的3-10%。可通过研究环境的回测看杠杆的大小，Trade_value可以小于Adjust_value，如Adjust_value的一半，这样相当于偏离指数2%的持有价值。
Adjust_value： 合约价值（USDT计价）调整偏离值。 当 指数偏离 * Trade_value - 当前持仓 > Adjust_value，即目标持仓和当前持仓的差超过此值，就会开始交易。过大调整较慢，太小交易频繁，不能低于10，否则会达不到最小成交,推荐设置为Trade_value的40%以上。

Trade_value不必说，直接关系到我们的收益和风险，如果Trade_value一直没改过，到目前应该是盈利的。
Alpha由于我们这次有了更高频的数据，显然也要1min更新一次才更加合理，自然要比原来小，具体多少可以通过回测确定。
Adjust_value一直推荐Trade_value的40%以上，原来1hK线设置多少都影响不大，有些人希望调的很低，这样就可以更加紧密的贴近目标持仓，这里将会分析为什么不应该这样做。
首先分析手续费的问题
可以看到在默认费率0.00075的情况下，手续费293,利润为270，比例非常高。我们把手续费设为0，Adjust_value设置为10，看看会怎样。

stragey_2a.account['USDT']

{'fee': 293.85972778530453,
 'leverage': 0.45999999999999996,
 'margin': 236.23559736312995,
 'realised_profit': 281.77464608744435,
 'total': 10271.146238,
 'unrealised_profit': -10.628408369648495}

Alpha = 0.001
#price_usdt_btc_norm2 = price_usdt_btc/price_usdt_btc.rolling(20).mean() #普通均线
price_usdt_btc_norm2 = price_usdt_btc/price_usdt_btc.ewm(alpha=Alpha).mean() #这里和策略一致，用了EMA
trade_symbols = list(set(symbols))
price_usdt_btc_norm_mean = price_usdt_btc_norm2[trade_symbols].mean(axis=1)
e = Exchange(trade_symbols,initial_balance=10000,commission=0,log=False)
trade_value = 300
for row in price_usdt.iloc[-7500:].iterrows():
    e.Update(row[0], row[1])
    for symbol in trade_symbols:
        price = row[1][symbol]
        if np.isnan(price):
            continue
        diff = price_usdt_btc_norm2.loc[row[0],symbol] - price_usdt_btc_norm_mean[row[0]]
        aim_value = -trade_value*round(diff/0.01,1)
        now_value = e.account[symbol]['value']*np.sign(e.account[symbol]['amount'])
        if aim_value - now_value > 10:
            e.Buy(symbol, price, round((aim_value - now_value)/price, 6),round(e.account[symbol]['realised_profit']+e.account[symbol]['unrealised_profit'],2))
        if aim_value - now_value < 10:
            e.Sell(symbol, price, -round((aim_value - now_value)/price, 6),round(e.account[symbol]['realised_profit']+e.account[symbol]['unrealised_profit'],2))
stragey_2d = e

(stragey_2d.df['total']/e.initial_balance).plot(figsize=(17,6),grid = True);

<Figure size 1224x432 with 1 Axes>

结果是一条直线向上，BNB只是带来了一点小小的波折，较低的Adjust_value抓住了每一次波动，没有手续费利润极佳。
如果有手续费，Adjust_value很小会怎样？

Alpha = 0.001
#price_usdt_btc_norm2 = price_usdt_btc/price_usdt_btc.rolling(20).mean() #普通均线
price_usdt_btc_norm2 = price_usdt_btc/price_usdt_btc.ewm(alpha=Alpha).mean() #这里和策略一致，用了EMA
trade_symbols = list(set(symbols))
price_usdt_btc_norm_mean = price_usdt_btc_norm2[trade_symbols].mean(axis=1)
e = Exchange(trade_symbols,initial_balance=10000,commission=0.00075,log=False)
trade_value = 300
for row in price_usdt.iloc[-7500:].iterrows():
    e.Update(row[0], row[1])
    for symbol in trade_symbols:
        price = row[1][symbol]
        if np.isnan(price):
            continue
        diff = price_usdt_btc_norm2.loc[row[0],symbol] - price_usdt_btc_norm_mean[row[0]]
        aim_value = -trade_value*round(diff/0.01,1)
        now_value = e.account[symbol]['value']*np.sign(e.account[symbol]['amount'])
        if aim_value - now_value > 10:
            e.Buy(symbol, price, round((aim_value - now_value)/price, 6),round(e.account[symbol]['realised_profit']+e.account[symbol]['unrealised_profit'],2))
        if aim_value - now_value < 10:
            e.Sell(symbol, price, -round((aim_value - now_value)/price, 6),round(e.account[symbol]['realised_profit']+e.account[symbol]['unrealised_profit'],2))
stragey_2e = e
(stragey_2e.df['total']/e.initial_balance).plot(figsize=(17,6),grid = True);

<Figure size 1224x432 with 1 Axes>

结果也走出了一条直线下跌的曲线，想想很容易理解，在很小的差价范围频繁调整，只会亏掉手续费。
综合来看，手续费水平越低，Adjust_value可以设置的越小，交易越频繁，利润越高。

Alpha设定的问题
既然有了分钟线，基准价格就要一分钟更新一次，这里我们简单回测确定下alpha的大小。目前推荐Alpha设置为0.001。

for Alpha in [0.0001, 0.0003, 0.0006, 0.001, 0.0015, 0.002, 0.004, 0.01, 0.02]:
#price_usdt_btc_norm2 = price_usdt_btc/price_usdt_btc.rolling(20).mean() #普通均线
    price_usdt_btc_norm2 = price_usdt_btc/price_usdt_btc.ewm(alpha=Alpha).mean() #这里和策略一致，用了EMA
    trade_symbols = list(set(symbols))
    price_usdt_btc_norm_mean = price_usdt_btc_norm2[trade_symbols].mean(axis=1)
    e = Exchange(trade_symbols,initial_balance=10000,commission=0.00075,log=False)
    trade_value = 300
    for row in price_usdt.iloc[-7500:].iterrows():
        e.Update(row[0], row[1])
        for symbol in trade_symbols:
            price = row[1][symbol]
            if np.isnan(price):
                continue
            diff = price_usdt_btc_norm2.loc[row[0],symbol] - price_usdt_btc_norm_mean[row[0]]
            aim_value = -trade_value*round(diff/0.01,1)
            now_value = e.account[symbol]['value']*np.sign(e.account[symbol]['amount'])
            if aim_value - now_value > 0.5*trade_value:
                e.Buy(symbol, price, round((aim_value - now_value)/price, 6),round(e.account[symbol]['realised_profit']+e.account[symbol]['unrealised_profit'],2))
            if aim_value - now_value < -0.5*trade_value:
                e.Sell(symbol, price, -round((aim_value - now_value)/price, 6),round(e.account[symbol]['realised_profit']+e.account[symbol]['unrealised_profit'],2))
    print(Alpha, e.account['USDT']['unrealised_profit']+e.account['USDT']['realised_profit'])

最近两月的分钟线回测结果
最后在看看长时间回测的结果。就在刚刚，一波此起彼伏的上涨，今日净值又新低，来给大家增强以下信心吧，由于分钟线的频率更高，将会在小时内开仓平仓，所以收益率会高很多。
还有一点，我们一直是固定的trade_value，这使得后期资金利用率不足，实际上的收益率还可以在增加很多。
在这两个月的回测时间内，我们处于什么位置哪？
