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.
