4.41  -  167  -  8/26/22  -  Current Release

ProTA 4.41 is a recommended upgrade adding several quality-of-life and performance improvements as well as minor bug fixes related to intraday line studies and some ProTAscript functions.

New Alert When Chart Backgrounds Are un-Editable

When a user sets Preferences to Set Chart Backgrounds to Match OS Light/Dark Appearance, all Chart Background color wells necessarily become non-functional.  This could cause a point of confusion, so we’ve added an alert for these situations reminding you of the setting with easy access to editing your Preferences.

Additional Bug Fixes, Quality-Of-Life and Performance Enhancements

* Intraday line studies now retain their intraday anchor date(s) when making edits in their inspector panel.

* Intraday timeframe Crosshairs tool now renders properly onto any other open Daily periodicity charts.

* Improved the global persistence state of all File Browser table column widths.

* File Browser's "Modified" table column  can now be shrunk to a more hidden width.

* Fixed potential app crash related to TickerIsInSuite() function.

4.4  -  166  -  3/25/22

New Indicator - Volume Profile

* Volume Profile displays the trading volume that has taken place at the various price levels within the chart. A unique plot style, Volume Profile renders as a horizontal histogram where each bar represents the number of shares traded at the corresponding price range.  

* Price ranges with low (shorter) Volume Profile bars (L), provide little trading resistance - trading moves quickly, higher and lower, through these areas.  


* Price ranges with high (longer) Volume Profile bars (H), reveal a battle between bulls and bears - these ranges commonly highlight expected support/resistance levels.  

* The price at which the most volume was traded will be the longest bar and is referred to as the Point of Control (POC).  


* The Value Area (VA), typically set to 70%, is the range of prices surrounding the POC such that 70% of the total volume is included in the VA. Highlighting the VA reveals where most of the trading has taken place within the visible chart.

New Price Highlighting Options

* Every chart plot’s popup display menu now includes new Price Highlighting options:

A chart with all three price highlighting options enabled:  High Bubbles, Low Bubbles and Y-Axis Highlighting.

* ProTAscript pragmas !Line1 - !Line5 have been expanded to accept an optional, fifth parameter to specify any of the three new price highlighting options in your Custom Indicator code.   The new, fifth parameter should be any combination of the letters H, L and Y to respectively specify the inclusion of High Bubble, Low Bubble and Y-Axis Highlight for the plotted output line:

!Line1(888888, 1, 0, 0, HL)

Gray color, normal line thickness, no dropline, no adornments, High & Low Bubbles.

!Line1(00FF00, 3, 1, 0, LY)

Green color, fat line thickness,  dropline, no adornments, Low Bubble & Y-Axis Highlight.

New !Text() pragmas to specify custom text and emoji output for your Content Tables

* Any ProTAscript formula can now include up to ten !Text pragmas to convert numerical output into text or emoji output when used in a Chart Suite’s Content Table.  


    !Text1(BUY) will convert the custom indicator’s output to the text BUY whenever the output evaluates to integer 1.


    !Text0(BEARISH) will convert the custom indicator’s output to the text BEARISH whenever the output evaluates to integer 0.


    !Text2(🔥) will convert the custom indicator’s output to the emoji 🔥 whenever the output evaluates to integer 2.

Range Ruler Now Includes Frame and Fill Options

* The Range Ruler Line Study can now render as a framed, and optionally filled, rectangle shape to better highlight trading ranges within a chart.

New ProTAscript Function TickerIsInSuite()

* It is now possible to test if the current ticker is present in any of your saved Custom Content Chart Suite files.  For example, you may have a saved Chart Suite where you have added your 30 favorite stocks.  Let’s assume this saved Chart Suite is named “My Favorites”.  One use for TickerIsInSuite() is to highlight these ‘favorites’ in any chart suite’s content table with a 💎 custom indicator column as shown below:

One-Step Adding and Removing Tickers To/From Both Content Tables and Global TickerPicker Database

* Often when creating a Chart Suite’s content listing, we need to add a new ticker - but sometimes that ticker does not yet exist in your global TickerPicker database.  You can now simply option-click on the + Rows button in any Chart Suite window to add a new Row while specifying a brand new ticker symbol, all in one step.


* Similarly, when reviewing items in a Chart Suite, we often find items that should be removed, not just from this particular document, but also from the global TickerPicker.  You can now simply option-click on the - Rows button in any Chart Suite window to remove the ticker from the current window as well as from the TickerPicker database.

Additional Bug Fixes and Performance Enhancements

* Choosing cmd-T when viewing a chart suite will now mirror the same ticker selection in the TickerPicker window.

* Added Remove Selected Tickers command to TickerPicker gear/contextual popup menus.

* Fixed issue pasting tickers into content tables when text included unicode/emoji characters.

* Custom Indicator plot Adornments now respect the !SkipZeros pragma.

* Sync Time Scale now better respects the X-axis "End With Last Date" setting in multi-grid chart suites.

ProTA 4.313 is a recommended update for all users including new hotkey features, automated syncing to iCloud for use with ProTA Mobile, updated Ticker Lists and several notable bug fixes and performance optimizations.

Automatically Sync Your Files to iCloud For Use With ProTA Mobile 

* Your ProTA Mobile app is always ready for a database sync with the new Daily or Hourly Auto-Sync options in the ProTA Mobile Sync window. 

* Click the new Gear widget in the ProTA Mobile Sync window to configure the timing of the automated uploads.

Ticker Lists Updated To Include Swiss Stock Exchange

4.312  -  160  -  5/11/21

ProTA 4.312 is an important update for all users including new and completely updated Ticker Lists, additional flexibility with several key ProTAscript functions, improved scrolling options for all charts, and over a dozen bug fixes and performance optimizations. 

Updated Ticker Lists


* When adding new tickers, the Ticker Lists now include new categories for Cryptos and Futures.

* All existing Ticker List categories have been updated with current lists from the various exchanges.



Additional Flexibility With Several ProTAscript Functions

* The following ProTAscript functions now accept computed variable (Array) parameters: AutoLRTL(), AutoRL(), AutoTL(), StdDev(), MA().  This allows for some entirely new approaches in some of your existing indicators.  For example, the code below now plots Linear Regression channels using a computed or specific start date of your choice:

Another example uses the new variable array Period parameter of the MA() function to compute the Hull Moving Average:

New Scrolling Commands

* Added Scroll Chart One Date Forward/Backward commands to the Charts menu as well as mouse-clickable areas on the left and right sides of the Time (X) Axis.

Easier File Name Editing

* Added Edit Name command to all source file tables' gear widget.

* Adding a new file to any authoring window now begins an immediate edit session of the “Untitled” default name.

Many Bug Fixes and Performance Enhancements

* Daily Trendlines are now hidden on Intraday charts to prevent misleading renders.

* Custom Indicator file and Trading System file modification triggers are now more strictly determined to limit unnecessary chart recalculations.  

* Intraday timeframe Crypto and Index charts will now update around the clock.  

* Reduced iCloud Sync file size by removing additional unnecessary files before uploading. 

* Improved timing fidelity of automated Yahoo sessions.

* Fixed issue with multiple crosshairs displaying when other windows were hidden to the Dock.

* Fixed a potential corruption issue when adding and removing many columns to a content table over time.

4.31  -  158  -  3/31/21

ProTA 4.31 is a required update for all users.  


In early 2021, Yahoo rolled out a new level of rate limitation for queries to its servers.  If your IP address exceeds the new new query limits (limits per minute, per hour and per day), your IP address is flagged for a period of time and you will not receive any responses from their server until the flag clears.  ProTA 4.31 complies with the new 2021 rate throttling levels, avoiding any flags, collars, or any other interruptions to your data updates.  


Version 4.31 also includes several improvements related to intraday data display and additional stability fixes.

Updated Yahoo Interface

* Improved the information provided in the Yahoo session logs (Tools menu: Logs).
