   /* Implementation of the SAR has been a little bit open to interpretation
    * since Wilder (the original author) did not define a precise algorithm
    * on how to bootstrap the algorithm. Take any existing software application
    * and you will see slight variation on how the algorithm was adapted.
    *
    * What is the initial trade direction? Long or short?
    * ===================================================
    * The interpretation of what should be the initial SAR values is
    * open to interpretation, particularly since the caller to the function
    * does not specify the initial direction of the trade.
    *
    * In TA-Lib, the following logic is used:
    *  - Calculate +DM and -DM between the first and
    *    second bar. The highest directional indication will
    *    indicate the assumed direction of the trade for the second
    *    price bar. 
    *  - In the case of a tie between +DM and -DM,
    *    the direction is LONG by default.
    *
    * What is the initial "extreme point" and thus SAR?
    * =================================================
    * The following shows how different people took different approach:
    *  - Metastock use the first price bar high/low depending of
    *    the direction. No SAR is calculated for the first price
    *    bar.
    *  - Tradestation use the closing price of the second bar. No
    *    SAR are calculated for the first price bar.
    *  - Wilder (the original author) use the SIP from the
    *    previous trade (cannot be implement here since the
    *    direction and length of the previous trade is unknonw).
    *  - The Magazine TASC seems to follow Wilder approach which
    *    is not practical here.
    *
    * TA-Lib "consume" the first price bar and use its high/low as the
    * initial SAR of the second price bar. I found that approach to be
    * the closest to Wilders idea of having the first entry day use
    * the previous extreme point, except that here the extreme point is
    * derived solely from the first price bar. I found the same approach
    * to be used by Metastock.
