The rank column was just for better understanding - but it failed :-)

   11. |  2     9      3      3        9 |

 this is how far I am now with the egen command. but I want a list like that:
       | id   bid   time   rank   maxbid |
    1. |  1     1      1      1       1 |
    2. |  1     4      2      2       4 |
    3. |  1     3      3      3       4 |
    4. |  1     8      4      4       8 |
    5. |  1    10      5      5       10 |
    6. |  1    12      6      6       12 |
    7. |  1    17      7      7       17 |
    8. |  1    14      8      8       17 |

With foucus on maxbid: not the total max of the entire list, but the max from 
bid[1] to bid[_n] for all _n's.
