Tsl not moving for me in BO

i have placed a bo for nifty futures @ 7719 with sl of 7709 (10 points absolute), and book profit of 7744 (25 points absolute) and tsl of 20 ticks. The future moved till 7034 and still my sl is 7709. Did I do anything wrong in placing this order. Should I convert all to ticks or to absolute to function. Please let me know. I have read the blog on BOs many times before placing this order.
