【解决方案1】：

我更正了你的代码，你可以在这里看到它https://www.tradingview.com/x/oERRUXom/，你不需要在收盘后添加零，因为这指的是图表中的最后一根蜡烛。接近零意味着接近

//@version=4 

strategy("Sagargy1", overlay=true) 
fast=20, slow=50 

fastMA= ema(close, fast) 
slowMA= ema(close, slow) 

strategy.entry("Buy", strategy.long, when=close > close [1] and fastMA > slowMA and close>vwap) 
strategy.entry("Sell", strategy.short, when=close < close [1] and fastMA < slowMA and close<vwap) 


plot(fastMA, color=color.green) 
plot(slowMA, color=color.red)
