P&F Charts - Change Parameters for Drawing Charts



Every stock has a number of parameters that are used to generate the charts and remembered between sessions.  In general these are:

  • Information about the latest changes in price data
  • Parameters used to change the way the Point and Figure Chart is generated
  • Parameters used to change the way the Line Chart is drawn

The following information shows you how to change these parameters for a given stock.








  1. When viewing the Point and Figure chart of the desired stock, tap the “Parameters” button
  2. The first section provides general information about the Stock (e.g. company name, exchange, currency etc).  Tap “Display Name” to enter a new name used to identify the stock on the Watchlist screen
  3. You can move the stock from one Watchlist to another by tapping “Watchlist”
  4. The second section provides general information about the Price data. Change the type of price data used by tapping “Price Time Interval”.  Choices include intraday prices (e.g. 15min), Daily, Weekly and Monthly
  5. Tap “Reload LATEST Prices” to refetch the last 10 periods of price data
  6. Tap “Reload ALL Prices” to replace the existing price data with all prices available on the stock server
  7. Scroll down and you will find a section of Parameters used to generate the Point and Figure (P&F).  Information on these parameters can be found in the references here or other reputable sources on how to use Point and Figure Charts.  The parameters available include:
    • Box Size Type : logarithmic (%) or arithmetic (set value)

    • Box Calculation Direction : “From Smallest” or “From Largest” - see here for more detail
    • Box Reversal : number of boxes before a change in direction is recorded.  Note: the app properly generates 1-box reversal charts
    • Calculation Method : which prices and algorithm is used to generate the chart : “Close”, “AdjustedClose”, “High-Low”, “Low-High” or “Open-High-Low-Close”
    • Data Period : how many months/years of data should be included in the chart
    • Show Months : should the month indicators (0,1,2,3,4,5,6,7,8,9,A,B,C) be shown on the chart
    • Display Precision : how many decimal places should be shown on the box prices
    • Bear Counts - Factor : Full or 2/3rds : used in calculating target counts
    • MA Period 1 : number of columns included in the first Moving Average line
    • MA Period 2 : number of columns included in the second Moving Average line

  9. Tap “Automatic” to let the app choose a suitable size for you
  10. Tap “Enter Your Own” to type in your own box size % or set size
  11. Tap any of the pre-set values to choose that one.

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.  If this happe

The app provides information (accessible via the 'Parameters' screen) about that Stocks exchange/region, time zone, currency and market opening and closing times. Prior to v2.0, the app converted dates and times to your local time zone but this was creating occasional confusion as to when a stock's data should have been updated.  Please also remember that AlphaVantage updates daily data after the close of trading fo
