* Filename: DayImpulse2DD.mq4
* Author: DriverDan, based on the original by Tartan at the link below
* Date: Nov 3, 2005
*
* Description: Sums the close - open for the past "per" bars and shifts it forward
* "drawShift" bars. Works very well at predicting movement.
*
* Signal2 is just the current bar's close - open shifted "drawShift"
* periods forward. This is what you see as the main signal draws. It
* isn't updated as time moves forward so that you have something to look
* back on.
*
* WARNING: Looking at past bars will be deceiving. It may look like it
* predicts perfectly on some pairs but remember that it is constantly
* updated. The most accurate live bar is the current one.
*
* The future is not set.
*
* Version: 2DD
* Released by DriverDan
* Almost all of the code has been changed or rewritten.
* Added Signal2.
*
* 1.1
* Released by DriverDan
* Fix horrible style, removed extra buffer, changed to draw from the
* beginning, added MA, and fixed gaps in signal.
*
* 1.0
* Initial release
