March 2025 – What’s New at TrendSpider

March brought another wave of updates to TrendSpider, aimed at improving flexibility, performance, and the overall user experience across multiple areas of the platform. From smarter AI strategy defaults to more powerful scripting tools, here’s everything new this month.

Quality of Life Updates

Volume by Price (VbP) Improvements

• The Volume by Price (VbP) indicator and chart annotation now support up to 100 levels, giving users a more granular view of volume distribution across price levels.

Watchlist & Favorites Improvements

• Custom watchlists now support up to 3,000 tickers, up from the previous limit of 1,000.
• Favorites (watchlists, indicators, scripts, etc.) are now stored server-side, so they persist across devices and won’t be lost when clearing cookies.

Bulk Actions for Color-Tagged Symbols

• You can now perform bulk actions on symbols marked with color tags, making managing and organizing your lists easier.
• You can quickly copy or move all tagged symbols to a new watchlist—or do the opposite, like moving only untagged symbols to a new list.
• You can also remove all tagged symbols from a watchlist.

Custom Scripting Updates

Project Indicators Into the Future with Ease

• Custom script users can now use the new paint_projection() function to extend indicators into the future on your charts.
• This makes it easy to visualize forward-looking signals, such as projecting a moving average beyond the current candle.
• Example usage:

jsCopyEditpaint_projection(sma(close, 20).reverse(), { color: 'red' });

Data Feeds Updates

New API Endpoint: Build Your Own Symbol Shortcuts

• You can now define shortcut symbols that automatically reference complex custom formulas or composite indices, making them easier to chart and reuse.
• For example, instead of retyping =(AAPL + MSFT + GOOG + TSLA + NFLX)/5, you can define a shortcut like #MYINDEX. From that point on, typing #MYINDEX into your chart will automatically pull up that custom data series.
• This feature is API-only for now, but an in-app interface is planned for a future release.

Cboe Index Agreement Changes

• Cboe has introduced new licensing requirements that split its index data into three separate agreement groups:
  • Cboe Main (e.g. $SPX, $SRO)
  • Cboe CGI (e.g. $RUT, $RLS)
  • Cboe FTSE (e.g. $TNX, $TYX)
• All Cboe index agreements remain free for TrendSpider users, but each group must now be accepted individually.
• To comply with this change, existing Cboe data entitlements will be reset. When you type in an affected symbol, you will be prompted to re-accept the agreements.

AI Strategy Lab Updates

Smarter SL/TP Defaults + Strategy Creation Safeguards

• Stop Loss and Take Profit levels are now automatically calculated based on the chart data used to train your AI model.
• This ensures you’re more likely to generate signals right out of the gate, unlike the previous hardcoded values of 0.5% SL and 1.5% TP.
• Additionally, we’ve added new validation checks to prevent invalid models from being created. For example:
  • Models won’t be created if SL/TP settings yield no signals.
  • You can’t use Linear Regression or Naive Bayes with multiple datasets.
  • You can’t use a Random Forest model with more than one dataset.
