Pine 脚本 - 如何在不同条件下测试策略

Question

希望你在这种气候下一切都好。我对 Tradingview 和 Pine Script 还很陌生，想运行对策略进行回测，但我在编码部分遇到了困难。我想在以下条件下建立多头头寸： - 5 EMA 跨越 10 EMA - RSI 大于 50 - ADX 大于 25

我想在以下情况下做空： - 5 EMA 在 10 EMA 下交叉 - RSI 小于 50 - ADX 小于 25

当 EMA 再次交叉时，应该平仓。我自己尝试这样做（见下文），但收效甚微。如果有人能给我一些指导，我将不胜感激。

和平:)

strategy.close("short", when = long)

closeLong = crossunder(ema5, ema10)
closeShort = crossover(ema5, ema10)

plot(ema5, title="5", color=#000000, linewidth=3)
plot(ema10, title="10", color=#002200, linewidth=2)

start = timestamp(2010,6,1,0,0)
end = timestamp(2019,6,1,0,0)

if time >= start and time <=end
    strategy.entry("long", strategy.long, 1000.0, when = long)
    strategy.entry("short", strategy.short, 1000.0, when = short)

strategy.close("long", when = closeLong)
strategy.close("short", when = closeShort)

// Debugging.
plotchar(long, "long", "▲", location.top)
plotchar(short, "short", "▼", location.top)
