What's the symbol for the minidow in IB?
You say you just want to monitor the bid/ask, so in your spreadsheet,
cell A1 will show the symbol
cell B1 will show the bid price
cell C1 will show the ask price
When the difference between the bid price and ask price is a certain number, then execute trade. Is that it?
Any other order details that will change for each order (e.g., quantity), or will they always be the same?
Please give an example of exactly how you want your spreadsheet to be set up.
