Place opposite orders. How?

[shivam007]

I want to place sell order if 1st closed order was buy and place buy order if 1st closed order was sell.
Example : -

1st order was Buy
2nd order should be sell
3rd order should be buy

like this.

How to achieve this ?

What do you exactly mean by '1st'? Do you maybe mean the 'immediately previous' trade?
