[STOCK] [Strategy][TRADINGVIEW][Tutorial] Using strategy.order in PINE SCRIPT to complete multiple trades strategy

 This article uses chatgpt for translation. [STOCK] [策略][TRADINGVIEW][教學] PINE SCRIPT使用STRATEGY.ORDER來完成多次交易的策略

Objective

In a trading strategy, if you want to add positions midway, you can use the strategy.order function to achieve this. The following example will be:

1. Buy once when it rises above the quarterly line, and the order quantity is 0.

2. Buy again when it rises above the 10-day line.

3. Sell all when it falls below the 60-day line.

P.S. If you don't want to sell all at once, you can adjust the quantity to be sold by adding the qty parameter to the strategy.close function.

  strategy.close("buy", comment = '全賣', qty = 1 )
