Strategy Description

实盘：https://www.fmz.com/m/robot/26018 这个策略适合长期看好比特币的脑残粉，使用价值平均策略来进行定投，可以有效的抵抗市场波动。（关于价值平均定投请度娘。）

基本的思路是先想好每个月想要投入多少钱（策略变量：MoneyEveryMonth），然后决定多久交易一次，交易的间隔不建议小于5分钟（策略参数：InvestInternal）。

以下用一个实例说明策略思路和买卖时机： 假设每月想要买入价值72000元人民币的比特币(便于计算)，每个小时交易一次，就是计划每个月交易24*30＝720次，每次计划投入的资金价值为72000/720=100元（变量A）。

小时B，当时价格C，已投入资金D，已买入币数E，现在币价值F，本次投入资金G， 本次买入币数H 1 400 0 0 CE=0 AB-F=100 G/C=0.25
2 200 100 0.25 2000.25=50 1002-50=150 0.75 3 1000 250 1 1000 1003-1000=-700 -0.7 4 500 -550 0.3 150 1004-150=250 0.5

最终的结果，投入资金300，买入0.8个比特币（价值400元），平均价格375元。

说明：程序会每次检查账户内的资金和比特币与启动时的差额，以此计算每次需要购买的数量，因此不要用其他机器人公用一个帐户，也不要手工进行买入卖出的操作。如果在交易所有充值和体现，应该在程序互动部分填入，否则程序计算会错误。
