Trade Order Execution Priority & Disclosed Quantity

Dear Traderji Experts,

Need your assistance in understanding the following.

my query is on "Disclosed quantity" and whether it has an impact on the priority queue of trade in the event of a partial execution.

For eg. I have placed an order for buying 1500 quantity of a share and disclosed the quantity as 150 (as per Min requirement 10%) at a price of Rs.12:55.

I could get 150 quantity executed and the rest 1350 was Pending as the share price went up to 12:60. After a while the share price returned to 12:55 but no execution took place even though I could observe multiple trades happening at Rs.12:55. http://www.traderji.com/images/smilies/annoyed.gif

As per my understanding partially executed lot stands the first priority over others orders by "time priority". Please share your thoughts on whether one has a disadvantage on order execution priority by disclosing partial quantity.

Disclosed Quantity - Disclosed Quantity field is particularly useful, in case, you want to trade this scrip in big volumes and do not want any panic reaction from the counterparties. In this field, you enter the quantity that you want to disclose to the counterparties and the same will be visible in the order book. For example, if you place an order to sell 1000 shares and put the disclosed quantity as 100, then the order book will show 10 sell orders of 100 each. Note! The disclosed quantity has to be a minimum 10% of the order size.
