Here are a few suggestions for anyone making a trading journal on here. i) Give explanations for your positions, rather than just state what they are. A call with no explanation is not meaningful information. You don't have to give away your exact strategy but some kind of trade reasoning is important. ii) Discuss your position size. Otherwise it is impossible to tell if call A is 10 times the size/risk of call B, for example. iii) Give some idea of your risk control approach, how you deal with losing trades, when and why you exit. How to manage risk and losing positions is an important aspect of any attempt to trade. iv) Give prices and times for entries, exits, and other position adjustments. Again they don't have to be exact but readers aren't going to check the time stamps of every trade in a journal, and without prices we have no idea how you are doing. v) Let us know your approximate results. You don't have to disclose exact $ figures, but % returns would be useful, and at the very least, a profit (or loss) vs amount risked is needed. Without this, there is no performance measurement at all. The ideal trading journal is one where any trader reading it can recognise all the important elements of trading, and see how the author handles them - how he or she struggles with the dilemmas of running vs taking profits, choosing appropriate size, exiting bad trades, handling drawdowns, implementing strategies in real-time with limited and changing information, and (hopefully) making profits and improving as a trader. Now, for reasons of privacy and so on, that ideal is rarely if ever reached. Most people don't post trading journals at all. But the closer you can get to it, the more useful, credible, and interesting your trading journal will be. There are also some kinds of journals whose goal is not optimal trading, for example someone might be doing a journal to instruct, in which case the size may be minimal; another might be experimental, so again large size is not going to be used; or there are ones done for PR or bragging rights, where the outright $$ P&L is not as important as the risk to reward ratio over the lifetime of the journal. And some journals preclude detailed discussion (e.g. intraday trading) because the timescale is too short to make live calls and posts. In such cases, an after-the-fact diary is the only option - but most of the other elements can still be discussed. Another way to look at it is to consider what would be a bad trading journal. E.g. i) posts trade entries only ii) no posted reasoning for trades iii) no posted price for trades iv) only posts exits on profitable trades v) no description of P&L vi) losing trades and drawdowns are not discussed vii) no analysis of errors, no discussion of lessons learned, no attempt at improving the approach or strategy viii) position sizes not disclosed ix) no hedges or partial profit-taking discussed x) no discussion of selection of best trade instrument xi) no discussion of position correlation xii) no trade planning discussion (i.e. what to do if the trade doesn't work out; how to handle unexpected events etc) I am sure there are many others I missed. Feel free to add your suggestions.
