Modifying syntax logic for NT

[tkaboris]

HI I am trying to write a logic to go long when last consecutive bars are bullish and about the same size.

ChatGPT throws sample code but its not good for NT. Can someone help to convert the logic?




double[] barSizes = new double[5];
bool[] bullishBars = new bool[5];

// Loop through the last 5 bars
for (int i = 0; i < 5; i++)
{
// Calculate the size of each bar
barSizes[i] = Math.Abs(Opens[i] - Closes[i]);

// Determine if the bar is bullish
bullishBars[i] = Closes[i] > Opens[i];
}

// Calculate the average size of the bars
double averageSize = (barSizes[0] + barSizes[1] + barSizes[2] + barSizes[3] + barSizes[4]) / 5;

// Define a tolerance for variation in bar sizes
double tolerance = 0.01; // Adjust this value as needed

// Check if all bar sizes are within the tolerance of the average size
bool similarSizes = true;
foreach (double size in barSizes)
{
if (Math.Abs(size - averageSize) > tolerance)
{
similarSizes = false;
break;
}
}

// Check if all bars are bullish
bool allBullish = true;
foreach (bool isBullish in bullishBars)
{
if (!isBullish)
{
allBullish = false;
break;
}
}

// If the last 5 bars were all bullish and of similar size, go long
if (allBullish && similarSizes)
{
EnterLong();
}
}
}
}

Hello tkaboris,

Thanks for your post.

From our experience at this time, ChatGPT is not quite adequate to generate valid compilable NinjaScripts that function as the user has intentioned. We often find that the generated code will call non-existent properties and methods, use improper classes or inheritance, and may have incorrect logic. We highly encourage that you create a new NinjaScript yourself using the NinjaScript Editor, and use the code generated by ChatGPT as more as suggestions and guide when coding the script yourself, than using the actual code generated.

While It would not be within our support model to correct these scripts at user request, we would be happy to provide insight for any direct specific inquiries you may have if you would like to create this script yourself. Our support is able to assist with finding resources in our help guide as well as simple examples, and we are happy to assist with guiding you through the debugging process to assist you with understanding unexpected behavior.\

To detect if the last 3 bars are up bars (green) you could create a condition that checks if Close[0] > Open[0] and checks if Close[1] > Open[1] and checks if Close[2] > Open[2].

To detect uf the last 3 bars are down bars (red) you could create similar conditions using the less than comparison operator (<).
