EA That check the leverage , spread of the instrument and open trade based on my selected size, at my selected time and direction

-Must check leverage XXXXXXX (0 means any leverage requirement) of the current instrument, (where i open chart) , or a instrument XXXXXX I specified  for example if i put 0.05 which mean the leverage is 5% based on the instrument specification , it will check if it stay 0.05 or change.  Example :If leverage requirements on the specification page change above 0.05 , the position will not open.

-Check spread XXXXX(0 mean any spread) of the instrument above  (based on PERCENTAGE) if I put 0.5 % it will check the difference between bid and ask price, is it more than 0.5%  . for example bid is 10 and if put 0.5%， ask should not be higher than 10.05.   (if put 0 mean wont care about the spread difference). Example : if the spread is higher than 0.5%, the position will not open.

If FULFILL above 2 condition

-open a position at XXXXX(0, mean anytime)  time i indicate, with XXXXX size 

-Able to specify either long or short XXXXX for that entry positon 

-I able to specify that this indicator stop working after certain position XXXXX has entered (if I set to one, this EA will stop working when there is 1 active position already regardless whether the position is enter just now or previous days, subsequent signal that fit the condition will not open a new position)
