ECN Trade Modifier

//+-----------------------------------------------------------------+
// On all MT4 market execution accounts (ECN, ECN Zero and Pro),     |
//preset SL/TP levels are not permitted. If a client wishes to add   |
//SL/TP levels, the client must modify the existing position after   |
//the order is opened. This EA helps a client effortly set a preset  |
//stop loss to a trade  a fraction of a second after it is entered.  |
//This especially helps in preventing huge losses whenever one is    |
//scalping on various financial instruments.                         |
