First attempt at a strategy not generating orders in back testing

问题

我是一个非常新的松树编程者（尽管我有C语言类似的语言经验）。

今天我编写了我的第一个用于回测的策略，但不管我怎么做，它都不会在测试范围内生成任何订单。没有编译错误。是否有人可以帮忙看看？

最初，我认为可能是时间范围的问题，但我似乎通过使用时间戳（字符串）覆盖来解决了这个问题，所以我有点不知所措可能是什么问题。顶部的注释解释了我的尝试。如果这是一些非常简单的东西，提前道歉。我仍然在学习的第一周。

// 这个策略有简单的规则 
// 多头条件：
// 1. 价格收盘低于EMA200
// 2. 价格收盘高于Trend Trader Strategy by HPotter线（另一种策略是用前一根柱子的收盘价穿越TTS线进行测试，目前已注释掉）
// 3. STC指标由shayankm制定的是绿色的
// 空头条件：
// 1. 价格收盘高于EMA200
// 2. 价格收盘低于Trend Trader Strategy by HPotter线（另一种策略是用前一根柱子的收盘价穿越TTS线进行测试，目前已注释掉）
// 3. STC指标由shayankm制定的是红色的
// 平仓条件：
// 下一根K线收盘（此策略旨在在1-5分钟时间框架或二元期权上进行高频交易测试）

I am a very new Pine coder (though I have experience in c-like languages). 

I have written my first strategy for back testing today, but no matter what I do, it isn&#39;t generating any orders in the testing range. There are no compile errors. Is there anyone out there who might be able to take a look at it?

I initially thought it might be a time range issue, but I seem to have that covered by using the timestamp(string) override, so I am a bit at a loss as to what may be the issue. The comments at the top explain what I am trying to do. Apologies in advance if it is something moronically simple. I am still in my first week of learning.

//@version=5
//This strategy has simple rules
//LONG when
//1. the price closes below the EMA200
//2. the price closes above the Trend Trader Strategy by HPotter line (an alternative strategy is for the close price that crosses over the TTS line in the previous bar - currently commnted out for testing)
//3. the STC Indicator by shayankm is green
//SHORT when
//1. the price closes above the EMA200
//2. the price closes below the Trend Trader Strategy by HPotter line (an alternative strategy is for the close price that crosses below the TTS line in the previous bar - currently commnted out for testing)
//3. the STC Indicator by shayankm is red
//CLOSE when
//the next bar closes (This strategy is intended to be tested for high frequency trading on 1-5 minute time frames or binary options)

你的代码有两个问题。

首要问题是`color.new(color.green, 20)`和`color.green`并不相同。因此，你的进入条件永远不会为`true`，因为你有一个条件像`mColor == color.green`。

你应该做的是，创建一个新变量来判断STC是否处于上升趋势（绿色），然后在你的条件中使用该变量。

```pinescript
mColor = mAAAAA > mAAAAA[1] ? color.new(color.green, 20) : color.new(color.red, 20)
is_green = mAAAAA > mAAAAA[1]
is_red = not is_green

enterShort = close < trendLine[1] and ema200 > close and is_red // 每个位于趋势线下方的位置的关闭
enterLong = close > trendLine[1] and ema200 < close and is_green // 每个位于趋势线下方的位置的关闭

下一个问题是，你不应该在回测脚本中使用barstate.islast和barstate.isconfirmed。在历史数据上，barstate.islast永远不会为true，而barstate.isconfirmed始终为true。

英文:

Your code have two issues.

The first and main issue is that color.new(color.green, 20) and color.green are not the same. Therefore your entry conditions are never true because you have a condition like mColor == color.green.

What you should do is, you should create a new variable to see if STC is in an uptrend (green) and use that variable in your condition.

mColor = mAAAAA &gt; mAAAAA[1] ? color.new(color.green, 20) : color.new(color.red, 20)
is_green = mAAAAA &gt; mAAAAA[1]
is_red = not is_green

enterShort = close &lt; trendLine[1] and ema200 &gt; close and is_red //the close for every position under the trend line
enterLong = close &gt; trendLine[1] and ema200 &lt; close and is_green //the close for every position under the trend line

The next issue is, you don't want to use barstate.islast and barstate.isconfirmed in a backtest script. barstate.islast will never be true on the historical bars and barstate.isconfirmed will always be true on the historical bars.
