Common Questions

What do you know about trading?
Well, we aren't just software developers, we ARE traders. The Trading Diary app is every bit as important to our own trading strategy as it will be to yours. We don't claim to know everything though, so we've enlisted the methods of the foremost expert on the psychology and methodology of trading, Dr. Alexander Elder. You can check his books out at the Amazon links on the Overview page. Trading Diary is based primarily on his teaching and writing.
Why should I spend this much on a trading app?
That's the first question we would have asked. Trading Diary is not a game. It's a tool for professional traders or those who want to really invest time and effort into making an income from the stock market. Trading Diary takes years of experience and pages upon books of knowledge and wraps it all into an easy-to-use app that is the equivalent of a several-week course. It's all boiled down to practical application, without the need to learn every detail behind the application. However, we also provide the links to all of the information that went into creating it right here in the description. You would spend a lot more to buy the books, not to mention the time that it would take to put it all together in a system. We've done all of that for you, at a significant savings to you of both time and money.
Is Trading Diary a Strategy for Trading?
No, Trading Diary is a tool to supplement your trading. It won't tell you how to trade. What it does is help you with risk management and provides a platform for tracking and reviewing your trades that will give you a complete picture of your trading history. Your ideas, chart images, and the data from your trades all come together in a way that will make learning from your mistakes and successes as easy as possible, so that you can become a better trader.
Why should I keep a trading diary?
The purpose of a trading diary is to learn and become better. When you are able to examine your performance in anything, not just trading, you can learn from your mistakes. Relying on memory or the simplified data available from your broker is not enough to form a complete picture. A trading diary lets you keep detailed information for that purpose. If you aren't learning and becoming better, you are wasting your time and money.
Is the Trading Diary app a standalone system?
Trading Diary is designed to work in conjunction with your desktop software. While Trading Diary should be essentially all you need to record and review your data, taking screenshots of charts and annotating them is easier from a desktop system. Trading Diary is also not a brokerage software, so you do not use it to actually execute your trades. It is a supplement to these systems.
I trade in futures. Can I use your Trading Diary for keeping records of my trades in futures?
Trading Diary supports stocks, futures, options, forex and any non-equity instruments. You can set up any instruments you trade in Settings.
I am an option trader. I do a lot of spreads. Do you have any examples of how to record a spread?
Presently, Trading Diary supports only outrights. Unfortunately, there is no easy way to record a spread trade using the Trading Diary software.
How do I setup point value for forex trading?
The point value calculation formula for Forex is very easy:

For direct rates:

Formula: Point value = lot size.
Example for 100,000 GBP/USD contract:
Point value = 100,000 (lot size) = $100,000 USD

For indirect rates:

Formula: Point value = lot size / current rate
Example for 100,000 USD/JPY contract currently trading at 120.50:
Point value = 100,000 (lot size) / 120.50 (current rate) = $830 USD
