i am sure with all your experience you could put your 2 cents in as well,
but in the mean time
how to follow multiple open orders,
1- get professionally trained in "order flow management"
2- get professionally trained in "time management"
3- get professionally trained in “project management”
*the above should take you 6 years full time if your good longer if not
5- then open your own business and run that for a minimum of 5 years
6-bringing us roughly too 11 years to complete, if your fast.
7- after you have completed the above successfully you would have gained the experience and knowledge you require to track multiple open orders.
simple once you have done the above…lol
