To normalize data the way Ben taught is to take one of the components and
divide by the sum of it and its related counterpart, such as UP/(UP=DOWN)
whether it is issues or volume or in this case the dollar value of the calls
and puts.
You can do it in Ensign because of the custom symbol feature. What you do
is take the $Calls/($Calls+$Puts) for each exchange. See the DTN symbol
list. Then for the total or the composite add all the $C for the
PSE,PHLX,CBOE,AMEX and divide by the sum of the $Total calls + $Total puts.
The ratios are a bit noisey ten to 15 minutes after the open so in my ELA
code I have a Time to start plot filter. Near the end of the day the total
ratio tends to drift downward as though the participants are leaving the
game. On report days, or days when a heavily traded optionable stock makes
news you can see that exchange ratio fingerprint it. Like around FOMC days
its intriguing to see how the option exchanges are betting on the outcome.
Last time they were all dead neutral at 0.5. I am able to do it in TS2k
because I have MetaServer between the dtn feed and the Global Server. That
way I can get at any component of the dtn stat symbols. Only the new issue
and volume dtn stats can be read by the TS2k GS. I bet Lawrence's NeoTicker
and the M2 or M3 has the capability to read the stat symbols too.
