So you'd know the mid point eg .0075 is a chi X trade ,there is ASX and chi XASX only shows on phone
ASX and chi X shows on laptop the chi X trades show up after the ASX trades in the market depth how ever they are seperate exchanges
if you select a price your bank broker looks for a better Deal on chi X if none there it is excited on to the price you set
If you pick at market it will trade in chi X first if there are any midway point sells to buy on chi x
When trying to get a mid way buy at market look on phone at course of sales when you see a sale at midpoint amount with cxxt on the right next to it means it was a crossed chi X sale exicuted by your broker ,this is the most likely time you can get a mid point trade on phone ,without looking on laptop market orders to see if there even is any there ,if that makes any sence ;-)
