[amibroker] How can I send a modify order to raise stop to breakeven after the first lot is closed?

[Padhu]

hi,

Hoping somone on this list can shed some light on this.

//// Forex trading using Amibroker using TWS API
Buy=some_rule; //Not as good as Japanese Forex Trader
Buy_level=valuewhen(buy,c,1);

exit1=buylevel+exit1_offset;
exit2=Trailingstop of 30 pips with initial stop at breakeven(Buy_level)  ( 
Initial stop loss set for 30 pips trailing below entry when long is entered)

If ibc.isconnected()

placeorder( for 2 lots)
sell lot1 at exit1
upon exit1 send order with exit2 condition.

Any ideas on how to do this?.
Thanks.

Cheers,Padhu
