Hi,
Also, please ensure you place the target and stoploss the correct way.
In BO, if you are buying a scrip at 100 and if you wish to keep Target at 105 and Stoploss at 97, then; you have to place the values as shown below:
Target = 105-100 = 5
Stoploss = 100-97 = 3
You have to place this difference value and not the actual stock price. This is very important.
If you wish to keep a trailing stop-loss, then you can keep it as 1.
Have you ensured you have sufficiant BO/CO margins for the trade?
