TrendSpider Software Update: Custom Scripting Upgrades

Hello, traders, and welcome to another software update from your friends here at TrendSpider! We are pleased to announce a significant update to our custom scripting which brings exciting new features and improvements that will enhance functionality and provide more options for your analysis. Details after the jump!

If you’re a developer or coder, this update is for you! In this release, we introduce major changes to our Custom Scripting functionality.

Using Additional Data Series

Using Multiple Tickers, Time Frames or Chart Types

It is now possible to request additional data sets within your scripts. You can utilize data from other assets, alternative time frames, or even other chart types, in any combination. If you have a script running on SPY, you can now request history for assets like AAPL, BTC, or , and utilize that data in any way you’d like including painting, computing indicators, and more.

Example: Rendering Premarket Price Range

This new functionality opens up the ability to do things like painting the premarket price action range atop a regular session chart. Doing this demands requesting an additional data set because a traditional chart will not contain said premarket data. The below image is a visualization of how this indicator will look when displayed on your chart. Source code is available in our Developer Docs.

Using Alternative Data: Unusual Options, News and more

Just as you can request additional data sets like mentioned above, you can now request any alternative data found on the platform. This includes items like news, earnings, short volume, market breadth, and more. A comprehensive list is provided below.

• News request.news()
• Analyst Ratings (US equity only) request.analyst_ratings()
• Splits (US equity only) request.splits()
• Dividends (US equity only) request.dividends()
• Earnings (US equity only) request.earnings()
• Insider Trading (US equity only) request.insider_trading()
• Short Volume (FINRA Reg SHO), US equity only request.short_volume()
• Unusual Options (US equity only) request.unusual_options()
• Popularity of a given ticker on Reddit (/r/wallstreetbest) over time request.wallstreetbets()
• Market Breadth (US equity only) request.market_breadth()
• Retail Traders Activity (US equity only) request.retail_trading()
• Federal Reserve Economic Data (FRED) request.fred_series()
• Crypto Fear & Greed Index request.crypto_fear()
• Dark Pool Volume request.dark_pool()
• Seasonality request.seasonality()

Example: On-Chart Earnings Marks

You can now do things like paint earnings reactions on your chart as bubbles. The bigger the surprise, the bigger the bubble. The bubble will be colored green if earnings were positive and red if they were negative. This is visualized in the chart below. Source code is available in our Developer Docs.

Example: On-Chart Unusual Options At Strike

Another use case is painting horizontal levels using Unusual Options data. In this example, horizontal levels illustrate volume at strike for puts and calls. The thicker the horizontal level, the higher the volume at strike. Source code is available in our Developer Docs.

New Line Types

There are now many new ways to render your indicators. Here’s a comprehensive list of all the new selections.

• Area
• Area Range (Vertical Range)
• Box Plot
• Bubble
• Column Range (Vertical Range)
• Stacked Histogram (Stacked Column Chart)

For these new chart types, there are a handful of things you should know regarding Painting Indicators, Assigning Colors, and Shifting Indicator Lines.
