//TOMORROW'S PIVOTS
//Description:
//I had been struggling with the code to Plot todays pivots from yesterdays price when using an intraday database.
//There were none available in the Amibroker library which plotted correctly the pivots for tomorrow on a intraday database.
//I checked the Amibroker forum AND found the following. Thank you goes to sdebu_2k. if you wish to go to the forum 
//search for "plotting tomorrow pivots". This routine provides todays quotes in the Title bar AND holds the todays pivots constant
//in the Title bar as well. The plotted pivots moves to the next Day when entering into the next Day. Absolutely brilliant! Thank you.//
