I Created the BEST ThinkorSwim Stock Indicator (Step-By-Step Walkthrough)

Education

Introduction

In this article, I will guide you through the process of creating a custom indicator on ThinkorSwim that effectively identifies strengths and weaknesses in stocks. By the end of this walkthrough, you will have a powerful tool at your disposal, which reacts quickly to market conditions.

Introduction

Indicators can significantly enhance trading analysis, and I have built a unique indicator leveraging Bollinger Bands. While Bollinger Bands are commonly used, they often react too slowly. My custom approach seeks to enhance the responsiveness of these bands, allowing for quicker identification of trend changes.

Understanding the Theory

The traditional Bollinger Bands method focuses on the midline to determine whether a stock is in an uptrend or downtrend. However, this can lead to frequent and rapid changes that might not accurately reflect market conditions. Instead, the goal of our custom Bollinger Bands indicator is to utilize the upper and lower bands but modify them to compare against previous values.

The new approach allows the upper band to track the lowest price over a defined number of past bars, and the lower band to track the highest price over a similar timeframe. This method provides a clearer picture of the stock's strength and weakness by requiring sustained movement above or below these levels.

Building the Indicator

Getting Started

We start by opening the ThinkorSwim platform:

  1. Navigate to your studies and click on "Edit Studies."
  2. Click on "Create" to initiate a new study.
  3. Name your study, e.g., "Bollinger Band Trend."

Plotting the Bands

Next, we will plot the upper and lower Bollinger Bands using Thinkscript:

plot HighBB = BollingerBands("length" = 20).UpperBand;
plot LowBB = BollingerBands("length" = 20).LowerBand;

Customizing the Bands

To enhance the sensitivity of the indicator, we don’t just plot static bands. Instead, we define variables to track the lowest and highest values of the bands over a specific timeframe (e.g., last 10 bars):

def lowBB = Lowest(HighBB, 10);
def highBB = Highest(LowBB, 10);

Painting the Bars

The next step is to color the bars based on their relationship to the new Bollinger Bands:

  1. Define the conditions for uptrend and downtrend using if statements.
  2. Assign colors (green for uptrends, red for downtrends, gray for indecision).
AssignPriceColor(if close > highBB then Color.GREEN else if close < lowBB then Color.RED else Color.GRAY);

Customizing Parameters with Inputs

To enhance usability, we use input variables to define the lengths of our bands, allowing for easy customization:

input HighBBLength = 10;
input LowBBLength = 10;

Now, users can change the lengths directly from the settings without altering the code itself.

Scanning for Strength and Weakness

Finally, this script can also be transformed into a scanner:

  1. Establish parameters to return stocks in uptrend or downtrend.
  2. Use the Scan feature in ThinkorSwim and apply custom conditions matching with our defined criteria.
## Introduction
plot scanUptrend = close > Lowest(HighBB, HighBBLength);

This allows users to find stocks demonstrating clear trends efficiently.

Conclusion

By following this step-by-step guide, you have successfully created a custom Bollinger Bands indicator in ThinkorSwim that reacts quickly to market changes. This can serve as a comprehensive tool for identifying potential trading opportunities as well as for building stronger trading strategies.
