1. The premise:The first time I learned how to write a strategy, I was commissioned by Ice Mountain: This article mainly refers to the strategy of the dam:https://www.fmz.com/strategy/188435In general, the strategy is not much different from the strategy of the big house, the writing is a bit rough.
2.前因When buying and selling digital currencies in bulk, the market price of the currency you want to buy/sell may be affected by the larger transaction amount.PullingI'm not going to sell it.The dishesI'm not sure. 1 pull: pull up the price, raise the currency 2 - Selling the coin directly, regardless of the price, causing the price to fall 3 Trading Currency Stocks: Currencies used for trading, such as the BTC/USDT trading pair,BTC is a trading currency.4 Value Currency Balance: The currency that the user charges, as in the example of BTC/USDT trading pairs, is the currency of the user.USDT is a currency
Ice Mountain commissioned:Operations: This is the process of automatically breaking down large orders intoMultiple assignmentsIn addition to the above, you can also set up an automated ordering system based on the latest buy/sell price and the price policy set by the customer.Automatic re-commissioning when the previous order is fully traded or the latest price deviates significantly from the current orderEffect: Reduce the impact of bulk buy/sell orders on the market price, making bulk purchases more affordableAvoid increasing your purchasing costs by paying large amounts to increase pricesIf you sell in bulk, you can.Avoid reducing your selling profit due to low prices caused by large sales orders
