Set TSL to specific value

I wish to specify that whenever profit reaches 1000, the TSL should start as follows

  1. Profit = 1000 - This is available under Trailing Stop Loss.
  2. TSL - Set it to 250 - This is NOT available under Trailing Stop Loss. But I wish to have it so that the cost (brokerage, taxes etc.) gets covered even if the trade goes in other direction.
  3. With every Rs.100/- increase increase the stop loss by 100/- - This is available under Trailing Stop Loss.
    so the contention right now is how to do #2 mentioned above. Please guide.
