* corrected param order Side -> Type, also corrected condition check for IsOrderPlaced * send open status for GetActiveOrders * GetActiveOrder() changes to include OrderID and status matching * BTC Markets batch order limit fixes & SplitStringSliceByLimit method BTC markets batch end points have limits (20 for cancel 50 for query) adds new method SplitStringSliceByLimit in common to split a slice by limit and return slice of slice * rm line :D * Added test for SplitStringSliceByLimit and moved to const * ntp client reworked to not return error if no valid time servers are found but default to system * clean up * new line added * use TimeMgr sublogger and wording correction on output * Moved to DialTimeout() & Removed SetDeadline call * removed line * added setdeadline fix * goimport file * removed unused error from NTPClient as we now default to system time if no server can be reached * Added checks for number overflows * converted to uint as you should not be passing a negative number in * Increased test cases for NTPClient * Removed Helper call as no longer outputting any data from function * removed unused param
