P&F Charts - What is the Box Calc Direction and what difference does it make?

The standard approach to calculate the box price values in a Point and Figure Chart is to start the smallest value up. This is the default. But you can select From Largest on the Parameter screen should you wish to switch to using the top-down approach.

For example, From Largest will take the highest data value plus a margin and then calculate the box values down the chart by subtracting the boxSize (or multiplying by 1 - boxSize% for logarithmic charts). From Smallest starts with the lowest data value less a margin and calculates the box values by adding the boxSize (or multiplying by 1 + boxSize% for log charts).

As with any P&F chart, changing the price values in the boxes can have an impact on the detailed shape of the chart and the emergence of buy and sell indicators. Changing the direction in which the box values are calculated (especially for logarithmic charts) will change the values shown in the boxes (by a small amount). Hence changing the box calculation direction From Largest to From Smallest can result in small changes to the P&F chart.

Both approaches are valid but From Smallest is the method used in most charting software (e.g. StockCharts). Chose one approach for a stock and stick with it.

Where is my data stored - can anyone else access it?

All of the app data is stored on your local device and, in the case of Clever Contacts or P&F Charts , in your own personal Apple iCloud account. It is not shared with the developer or available to anyone else. Only those that have access to your devices have access to your data.

P&F Charts - no prices?

Sometimes you may see a stock reflected in a watchlist that shows NO prices like in the example above. This happens when you have added a new stock on a different device connected to the same iCloud account. The stock details have synced but the price data does not (by design). Just tap on the stock and the app will automatically try and fetch all the price data from our stock supplier for you.

P&F Charts - Where does the Stock Data come from?

P&F Charts sources all of its stock data from the Alpha Vantage service. This is an amazing service which provides a huge range of daily stock prices for stocks, indices and currencies from all over the world. See their website for further information. It is also important to remember that AlphaVantage update the daily prices sometime after the close of trading for a specific stock. If you want intraday data, try using an intraday interval (e.g. hourly). You can change this on the Parameters screen for a specific stock in your watchlists. However, it sometimes (not very often) inexplicably drops a particular stock for some period of time. The search will say they support it (and probably did until yesterday) but will report no data available when asked for the latest prices. Unfortunately this is completely out of our control and Alpha Vantage unfortunately does not have a support capability that can answer questions about particular stock price availability.
