Block Trades

AS we discussed What I am looking for is the block [login to view URL] my times and sales window on Ninja trader i can see the size of every trade in the market. For example last BUY quantity was greater then X. = BUY Quanity @ market On another note, we dont want to enter multiple orders in the same direction. Ex: X = 100 Market Times and Sales: 09:12 ES BUY 100 @ 2098.00 09:12 ES BUY 100 @ 2098.25 09:11 ES BUY 200 @ 2097.75 We would want to Buy at market price just once. 09:15 ES SELL 100 @ 2090.00 09:14 ES SELL 200 @ 2090.00 We would sell out of our position. Then wait at least 1min before looking for next entry.
