How to use Trailing stop loss in BO order?

In Pi trailing stop loss is mentioned as ticks ONLY. If I use Absolute for my target and SL, should I use ticks (1point=20 ticks) for trailing stoploss? I want to use 2 points (Absolute) target and 1 point (Absolute) SL and Trailing stoploss I want to use 0.25 points. Should I write 0.25 or 5 in place of Trailing Stop loss while placing BO order? I used 5 but it didnt worked and I lost money though the price went +1 point after my trade and dropped to -2 at the end and made loss as it squared off with SL. Please explain if someone got the answer for this.
