ObjectsTotal() & OrdersTotal() for-loop array ?

//-- loop total horizontal lines on main chart

for(int i=ObjectsTotal(0,-1,OBJ_HLINE); i>=0; i--)

this should begin a count on horizontal lines beginning with 0 if there are no horizontal lines ??

and this means that if there were no horizontal lines that it would process the for loop with no object ??

the documentation says it returns the amount of objects - not that there is an array with 0(0 objects?)

now, what about this..

//-- loop open positions

for(int i=OrdersTotal(); i>=0; i--)

this is not unlike the ObjectsTotal() and would mean there is an ordertotal of 0 that could process a loop ??

so shouldn't these be like this ?? ::

for(int i=ObjectsTotal(0,-1,OBJ_HLINE); i>0; i--)

for(int i=OrdersTotal(); i>0; i--)

..the loop will not process if there are no objects or orders.

  for(int i=ObjectsTotal(0,-1,OBJ_HLINE)-1;i>=0;i--)

if there are no objects then i's initial value will be -1 and the loop will not be executed.

no objects or orders the value is 0.0

Ok thank you!
