// NOTES:
// - Sometimes you might experience, when their stop-loss/take-profit order might not become activated, even though on chart the price had crossed that "trigger-price"       order was not executed . That happens because some exchange might be using mark-price (instead of last-price) as a reference-price, so that mark-price might reach your trigger-price and it would activate your SL/TP order (even though on your symbol's chart you are viewing the "last-price" by default, which could have different movements than the mark-price).
