kongbai979 self.vol到底是个啥？是一个ticker期间内所有交易量的总和吗？

dayTrader2018for (var i = 0; i < 15; i++) { self.prices[i] = trades[trades.length - 1].Price }; is there a bit of a problem here, so isn't every element in the price array the most recent transaction price?

kouyou7035I have several exchanges with no fees and good trading depths. Can you try this strategy?

bijiasuoIt's great, I'm sorry it won't work, is it working now?

rajajackIf anyone has tried it, come out and discuss the benefits.

valennnWhen will the annotations come?

wuqianmingHow do you run a botvs unsupported, free-to-trade exchange, how do you write an exchange API?

JThank you for sharing such a great strategy! exchange.CancelOrder ((orders[i].Id) The code for cancellation has a bit of a problem with the constant cancellation of orders. If you look at the original code below, you should have waited 10 seconds to withdraw it. The rest is basically fine, and I've changed it to run on a fee-free exchange, which feels good.

1213761768It's too early.

Chang is unyielding.No, the bid price has to be less than the ask price, one is the bid price, one is the sell price.

bwxiaokPlease, when calculating bid price and ask price, the order is placed as if the bid price is not greater than the ask price, so if the buy and sell is very close, the calculation is very likely to be high buy low sell, will there be this problem?

I love the fluff.I wrote a commentary that everyone needs to be able to add my Weibo post Hoo_tongxue, and most importantly, it's free.

akkk 请问zaif.jp现在还是免手续费吗？怎么通过认证呢

xiahaohuan001See the ID.

J 在Zaif.jp上测试，买一卖一间经常就没有空间，用这个策略有什么问题吗？

JIs it true? Come out and give a lecture.

xiahaohuan001Surprised by Author

JGood, I have a few more questions, please, and another post: https://www.botvs.com/bbs-topic/677

ZeroIf you have any questions or lessons to share about this strategy, please post them in the forum, thanks for your support!

ZeroThanks for the suggestion, I added a parameter, balance order waiting time, if you want to process simultaneously, you can record the ID of each order with the time of ordering, and then selectively cancel, so as to reduce the delay, but logically, should be first balance re-opening, because not all exchanges support the Time attribute to get the order, so the platform does not add this attribute in the Order, needing its own statistics.

xiahaohuan001I feel like it's a weird strategy, I like it.

ZeroI haven't tried this, so I need you to do your own research.
