var Alpha = 0.001 //指数移动平均的Alpha参数，设置的越大，基准价格跟踪越敏感，最终持仓也会越低，降低了杠杆，但会降低收益，具体需要根据回测结果自己权衡

var Stop_loss = 0.8

var Min_diff = -0.3 //当diff小于-0.3时，不继续加多仓, 自行设置

var Alpha = 0.001 //指数移动平均的Alpha参数，设置的越大，基准价格跟踪越敏感，最终持仓也会越低，降低了杠杆，但会降低收益，具体需要根据回测结果自己权衡
var Update_base_price_time_interval = 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

//Stop_loss设置为0.8表示当资金达到低于初始资金的80%时，止损，清空所有仓位，停止策略。
//随着策略运行，Stop_loss可以设置大于1（重启生效），比如从1000赚到1500，Stop_loss设置为1.3，则回撤到1300元止损。不想止损可以把这个参数设置的很小。
//风险是大家都用这种止损会形成踩踏，加大亏损。
//初始资金在状态栏的init_balance字段，注意提现等操作会影响，别不小心止损了。
//如果还是怕黑天鹅事件，比如某个币归0等，可以手动提现出来。

tiagombalsa @tmbs95 add me on telegram, interested

The bride too.Please tell me, in the function onTick ((), there is a line like this, assets.USDT.long_value-assets.USDT.short_value <= 1.1*Trade_value, I understand that this is set to prevent too much space imbalance.

mikelslCan't find it on WeChat?

Capital of the Exchange ChainMax_diff and Min_diff aren't supposed to be 0.04 and -0.03?

The Air Force will never be a slave.Give this closed circle a little bit of sunlight.

Quantification of district classesThe person suggested to do more overshooting to do nothing overshooting strategy to eliminate the BNB, this deal is the BNB wanted to attract popularity, it is estimated that the overshooting; can not be seen from the historical perspective now

The bride too.This is two things.

The bride too.A coin goes out of the independent market, this multi-space balance setting can prevent big losses, so the decision can not be imbalanced. Only to find a way to open a hedge account. Now the various currencies are bullish, feeling unsuited to run this strategy, the retracement is a little big.

The grassYou are wrong, wangweibing_ustb

izhangsanIn fact, if you look at the code, you will know the results of the retest of the entire currency, no need to worry. In the addition, Alpha = 0.05, add LINK, ETC, BNB, the initial historical retracement is 3%, the maximum retracement of the extreme market is less than 25%, Trade_Value with 3% of the safe over-total currency.
