HAVE:
A script that can read one or several matches from a database and simulate a betting strategy against these matches. Output in a processing window on screen. Result is updated in database.
(for better understanding of how back/lay is working, look at [login to view URL])
DATABASE:
MATCH contain match information, ODDS contain all odds movement on the matches.
ODDS for a match can exist for every second of an match or for those seconds where odds is really changed. An entry contain a certain second of a game and include odds for both players (3 levels)
WANT:
A graph displayed before simulating a match on screen. Y=Odds, X=Time. During read through ODDS for a game, display a vertical line moving on the graph in X column.
Change 1) User can actively choose if he wants graph or not (Graph On/Off). Graph will instant display or be removed. Default On
Change 2) Is user select/change/update a strategy (current function), the graph is updated with first match displayed
Change 3) Click on a ">" arrow will show replace graph with next match, click on "<" will update graph with previous match.
During simulation:
Change 4) Click on [SIMULATE] (simulate all) will update graph before each match is processed
Change 5) Click on [SIMULATE (step)] will do the same as above (currently there is a pause after each game)
Graph:
Change 6) Graph is fixed size and consist the odds movement of a game (x=time, y=odds). Draw x lines showing odds changes during time.
Changes 7)
Option1) A "lines:" option menu affects the amount of line on graph.
Option2) A "scaling:" option menu affects the X (extrapolate or not)
Option3) A "Time display" option affects when to display time on graph
Option4) A "Follow" option menu decide how user can follow time during simulation
Option5) A "Simulation speed" option (slider) where speed of simulation can be setup. (I imagine it requres a simple php pause function
My question for you:
-What library do you suggest (no flash)
-How to implement vertical line that moves across graph (during read of odds)
