i.e., does not change the relative order of elements | //|with equal keys | //| | in-place; i.e., only requires a constant amount o(1) of | //|additional memory space | //| | online; i.e., can sort a list as it receives it | //+------------------------------------------------------------------+ //+------------------------------------------------------------------+ //| script | insertion sort example. sort deals by type | //|------------------------------------------------------------------| //| on start | script program start function | //+------------------------------------------------------------------+ #include <Mqh\Algorithms\SortInsertion\InsertionSort.mqh> #include <Mqh\Algorithms\SortInsertion\Functions.mqh> void OnStart(void) { //--- load deals from the terminal for some arbitrary date range in //the past. these are the items array for the sorter ulong deals[];

Buy using amount instead of lots
I find the lot calculation tedious so I just use this script and tell it the dollar amount to use. It then does the rest. This works for any currency.
