Plan, Manage, Review

Trading Diary is a complete solution to help you become a better trader — from planning your trades for optimal risk management to reviewing them for improved performance in the future. This app is packed with tools you may have never considered, but will become essential to you in your future trading success.

Comprehensive Overviews

Trading Diary records every aspect of your trades from beginning to end, from your initial reasons for the trade to an easy-to-use grading system, so that you can see at a glance where you went right or wrong. Hindsight is 20/20, and Trading Diary will give you the clearest vision of your trading career you've ever had.

Avoid "Shark and Piranha Bites"

The impeccable risk management system of Trading Diary, based on the methods of Dr. Alexander Elder, is designed to keep you from over-committing and over-trading. Getting 'shark bit' by huge losses when over-committing can paralyze you when getting back in the water. 'Piranha bites' are smaller losses that accumulate to take you under when you over-trade. Trading Diary uses reasonable risk guidelines to help you keep your confidence high when it's time to pull the trigger on a trade.

Results you can see

The brilliant calendar navigation and graphic statistics of Trading Diary ensure that you can always find the information that you need from your trading history in a snap. From the big picture to the smallest detail, you will always know where you stand and how you got there.

User reviews

    • The trading diary app from Plum Square is a powerful and easy-to-use tool for everybody who wants to document and analyse their trades directly on the iPad. The risk- and money-management function helps to stick to the risk limit and offers valuable services calculating position size. At a price of 159.99 EUR, the app seems expensive at first glance, but if you look at the extent of functions and features the price is justified. Thumbs up!
