New Release: v2.0.0 - New Everything

Major changes to just about all parts of TS. Instead of reading below, maybe you should just think of it as a brand new bit of software.

Fixed Or Added In v2.0.0

  • Wizards - to help you out with Getting Started, Trading Systems, Alerts, Accounts, Users, Data Manager entries, Backtest config entries, Outgoing email, Receiving email, SMS, Holidays.
  • Can now import and export Trading Systems and Alerts. Useful for backing up, restoring, moving between your own computers, or sharing with others. You have the option to encrypt them so nobody else can import them without the password you set. When imported, encrypted Trading Systems and Alerts will not show their inner workings. They will still backtest/auto-trade/alert though. So you can sell your systems but keep your secrets.
  • Backtesting no longer relies on Microsoft Excel. All results are now stored in the TS database. You can search on past results. You can also view a result, and you will be shown an equity curve and some other charts of the results. Click a button, and the Chart window will open, be filled with the price data you just backtested with, the indicators used in your Trading System will be added to the chart, as will the entry and exit points.
  • All search field values, window sizes and positions, are now stored and re-entered automatically next time you open a window.
  • Now have the ability to decide if you want a message created to remind you to connect to the Internet X minutes before the subscription check is done. You decide if the message is created, and if so then how many minutes before.
  • The "Trade Mgmt Only" setting no longer resets a trading system to "Disabled" after all of its open trades are closed. Instead the status will remain at "Trade Mgmt Only". Which means you can continually open trades manually and have TS take care of the trade management part for you.
  • New colour scheme and icons.
  • Subscriptions window has changed a bit. No longer big and ugly.
  • Default Chart colours now prettier.
  • Can now have multiple Chart windows open at once.
  • Now has a confirmation message before closing TS.
  • Trading Systems and Alerts no longer started by a countdown. They are started when new price data comes in.
  • Close button put on all windows.
  • Outlook-style toolbar to assist with navigation.
  • Gain Capital now offers CADJPY, EURCAD. Oanda offers EURTRY, USDTRY, USDCNY, USDINR and USDTWD.
  • New Oanda transaction description - Order Expired. Set order status to cancelled.
  • Put "View Data" & "View Charts" menu items on Data Manager. They open those windows and set the search criteria to match the highlighted Data Manager entry (user then clicks Search button themselves).
  • "Table Name and Row count" menu item on the Data Manager. Shows how many bars of price data currently stored for the highlighted Data Manager entry.
  • All passwords now encrypted.
  • Add more detail to long and short icons (green and red arrows) so that when hovering the mouse, the date and price is also shown.
  • Have user option for which trading system to set when unknown. Default to "Unknown".
  • Overbought and oversold settings for Detrended Price Oscillator are now to 5 decimal places instead of 1.
  • Can now display all rows instead of maximum 500,000. Be careful with that though.
  • Maximum Adverse Excursion (MAE) value not correct when the initial stop loss is taken out. It's fine if the stop loss has moved and is then taken out.
  • MB Trading and EFX Group now allows multiples of 1000, not 10,000.
  • [OHLC] Minus X Average True Range(s) and [OHLC] Plus X Average True Range(s) would add the ATR in terms of pips. E.g. for EURUSD, instead of 1.2345, the end result would be like 75.2345.
  • RSI Signal Line Is Falling and RSI Signal Line Is Rising rules need "Signal period" parameter.
  • And various other little bug fixes, tidy ups, and miscellaneous changes.

Video Tutorial On How To Copy Your TS Database

Thanks to some freeware called Wink, there is now the first of probably many video tutorials on how to use TS.  Except that this first one has nothing to do with how to use TS :-)  It guides you through making a backup, then restoring, your TS database.

The reason I made this one first is precisely because I made sooooo many changes to TS that there's a high chance I broke something.  And that's why I'm calling v2.0 "beta" to start off with.  And that's why you should make a copy of your TS database, and test v2.0 on that copy.  When you're happy that TS is working just fine for your purposes, then you upgrade your original database (or just keeping using the copy.  But in either case, making the copy is important).

The backup file is a plain text file, which you can copy somewhere safe in case the computer running TS dies, is stolen, catches on fire, etc.

This procedure is useful for:

  • Taking a simple backup for safe-keeping.
  • Copying your live database so you can test a new version of TS.
  • Copying a TS database from your local computer to a different computer (e.g. a dedicated server you just started renting).
  • Moving your TS database to a new version of PostgreSQL, when you upgrade that.  (Necessary when moving between major revision numbers, e.g. 8.1 to 8.2, but not when upgrading from 8.1.3 to 8.1.4).

So take a look.  At the moment I've just uploaded the direct output from Wink, which is a very plain webpage with an embedded flash video.  Click your browser's "back" button to return to the TS website proper.

Backup, Restore, Copy, Move Your TS Database

Suggestions welcomed.
