Could you help me on how to do the following:
BB1 is in a trade on S1 (Stock 1) but the order is only partially filled. In the mean time, BB2 receives a triggering signal and needs to:
1. close out the S1 order BB1 is in and then
2. fully use all remaining buying power (ad-hoc calculation of # of shares) to enter a trade on S2, firstly using a limit order and having the trade partially filled and after the price has changed a specific delta (eg, $1), close out the partially filled order and enter a market order using all the remaining buying power.
If possible, could you demo it in this week's training? Thanks in advance!
