In 2.4.3 we fixed some critical errors associated with profit calculation. We also improved put price estimate and fixed some bugs related to exit plans. We added hundreds of unit tests to make sure margin of error is within 1/10th of a cent.
2.4.3 also introduced new feature for Exit plans. When designing an exit action such as adding, closing or rolling an option, user can also adjust action date and the stock price, volatility on that date. This allows user to experiment and find the best scenario for his desired exit plan.
We constantly improve this app and release new versions. App update is automatically enabled by default on iOS, so you don’t need to worry about it. Otherwise please don’t forget to turn on automatic update. The size of the app is small, just around 20 MB.
This issue only affects overwritten costs. If you overwrite the cost of your strategy, when you close a position or roll an option in the follow-ups, the profit calculation (including the chart) is not correct. An emergency fix is applied. You will see the fix in the next version 2.4.3 in the coming week. Sorry for the inconvenience.
If you found any issues, please don’t hesitate to report to me through email@example.com or the in app suggestion box. We’ll post any serious issues that might impact your trading and profit in this forum. Other minor issues will be prioritized according to severity.
In Optactic 2.4.1 user can overwrite the computed cost of the strategy. To find this feature, in the strategy creation screen or strategy details screen, click the “More” text button next to the strategy info panel (where it shows Cost) so that the strategy info will be expanded. At the bottom of the table of information, you will find the “Overwrite Cost” button, right next to the “Reset Cost” button. Click on the “Overwrite Cost” button will show the overwrite dialog box, where you can enter a cost value to overwrite the computed strategy cost. The “Reset Cost” button will reset it back to computed cost.
In most cases you don’t have to overwrite the cost, and I’ll explain why in a moment. There is one case this feature is useful. Sometimes you want to add an existing position, but the only information you have are the options and the price you paid for that strategy. In this situation, there is no way to accurately compute the cost since it requires information about the underlying stock price and volatility at the date of purchasing the options. With the overwrite cost feature, now you can add any strategies you already own from your brokers to Optactic.
You might be tempted to overwrite all strategy cost with the actual purchased cost, but I’d strongly suggest no. The reason is that this will skew the accuracy of calculation. Optactic uses Black-Scholes model to compute the value of options in all its simulation. The Black-Scholes model uses volatility of the underlying stock as one of its input. In order to get consistent result, you should use the same volatility model for all the inputs. For example, using either 90-days standard deviation or a weighted composite implied volatility. The cost you overwrote reflects an implied volatility that includes information of specific supplies and demand of that specific call or put, and it has nothing to do with the overall stock volatility over periods of time.
Hope you will enjoy this feature.
