I am a new member of the Forum and a very unexperienced trader who constatnly looks for new ideas.

I am a swing trader. I reverse my position every 2 - 4 days based on an indicator that I bought (I do not show the name of the indicator because I do not know if the Forum allows to show the stuff that is not free). Please see how it works on the attached print screen. When the blue line goes up and red dots appear above it, I reverse into short. When there are green dots above, I reverse into long.

I am from Europe (forgive my English). Our exchenges offer 'open interest' data in ticks, while US exchanges offer 'open interest' data daily only. Open interest in my local exchange varies from 50,000 to 80.000 during a week - that is a huge fluctuation.

The indicator that is shown in the print screen works perfectly on 20 minutes bars so far. But it will eventually mismatch 20 minute bars and my signals will become less and less accurate with time.

I was thinking of how I can make this indicator resistant in time and one idea flashed my mind. I was wondering if any of you guys came accross a charting software that allows to create bars based on a number of contracts traded as percentage of overall open interest.

It is my guess (I may be totally wrong here ) that when I replace my time bars with the ''bars based on a number of contracts traded as percentage of overall open interest'' - sorry for this lenghty and hard-to-understand phrase - I could get adequate signals no matter what wolume and time.

Could I get your opinion on this concept?

Why do you think that open interest has any relevence? There is a huge amount of daytrading that does not give any change in open interest.

Most charting packages have Volume bars that allow you to chart bars of a constant volume. Most traders that use this form of charting use an amount of volume that gives the number of bars persession that suits their style. As a daytrader, I use volume bars that give me between 200 and 300 bars per session.

If you really want to have volume bars dependant on open interest, its a matter of looking at open interest periodically and then manually changing the number of contracts required to create your volume bar.

Momentom, I was thinking the same and it should work that way, except for the daily's or higher because open interest changes but you usually are only able to specify a fixed volume.

That being said, I doubt you'll be able to find a multi day charting package which can do that.

Fascinating idea Tresor.

Which exchanges give real time open interest? That would give an intraday trader a potentially huge advantage. Coupled with volume you would know if people where buying/selling to open/close positions.

Momentom I think you might of mis-read the original post , Tresor is saying on the exchange he trades that you can see the change in OE on a tick by tick basis. WOW!

Hello momentom,

Many thanks for your reply. You are definitely right when saying that open interest is of no relevance for a daytrader.

Believe me, for me the open interest does have some significance. If there was no significance to OI nobody would have deviced the Herrick Payoff Index that analyses volume, price changes, and open interest changes to determine the amount of money flowing into or out of a futures contract. http://www.forexrealm.com/technical-...off-index.html

As I mentioned I am a swing trader. I reverse my position on average every 4 days. OI can change (which often happens) by as much as 70% durring these 4 days.

Below are some of my findings:
- if OI is 40 thousand and I work with my oscillators on bars that shows, e.g. volume of 1000 contracts then my oscillators work perfectly;
- but when the OI rises to as much as 80 thousand my oscillators are less accurate (to say it gently) on 1000 contracts' bars (and I have to adjust the settings of my oscillators or use time bars) - this is my biggest pain in the ass. Why shouldn't a machine filter the volume bars by OI?

I believe this seems somewhat abstract to guys who do not have OI in ticks.

I was merely interested if there is any software that I can produce volume bars filtered by OI.

Regards

Hello BlowFish,

I am from Poland.

Attached is a red price action and blue open interest (both in ticks).

Frankly saying I have already spot some repeating patterns between price actions and the way OI behaves.It really is fun to see where the dumb money is buying or smart money is getting short just by observing some curvatures of OI. I will post some jpgs when discussion is on

I believe most East European exchanges offer OI in ticks. And if I am not mistaken also France.

Just between us, I belive the volume is very important. If one could only filter it by OI...

Regards

Tresor - really fascinating idea ... and how cool is it to get OI that is so much more up-to-date than what is offered on US exchanges!

I am going to look more closely at your chart ... great thread thanks.

And following on from Mister Ed and BlowFish, I think it sounds a great idea, and I'm very interested to hear more as I trade the Eurex. Please could you explain more on how you incorporate it into your trading.

Cheers
