Have a filter for the overall account that caps the trade size at a % of the average daily volume. Or the lowest low volume in the past N months (user settable). So OmniVest would limit the size of the trade to say 1% of the lowest low volume in the last 2 months to make sure your positions aren't too big. This could also be a benefit because as the accounts gets bigger it can start using more strategies as the original ones will start having their trades capped, giving you more diversification.

With the number of strategies playing in the same markets, there are often times where the recommended number of shares to purchase from four or more strategies exceed 30% or 40% of equity. Perhaps in addition to maximum $ amount or maximum trade size, an addition of Maximum Percent of Account Value per Equity would save excessive risk of underdiversifying.

Yes, this is very good recommendation. I have a portfolio with over a dozen strategies and have scene the same stock symbol selected three times. So this would be very helpful to lessen the exposure to one stock.

I believe that the pct input just provided should automatically be applied to the net of all strats and portfolios in any account. It's purpose is to prevent slippage and keep trades diversified and realistic.

Furthermore and very importantly - I believe that the percentage should also take into account any EXISTING shares on a given symbol, when a new signal tries to add to them on that symbol. Same reasons as above apply.

I don't see any benefit in having two or three separate percent inputs for this - that would confuse matters. Proper money mgmt should look at the whole account, and integrate new sigs with existing positions, for this purpose.

This is REALLY important. Thanks for posting about it.

I think Jim and Barry have captured the essence of this well, (existing shares + proposed new shares)<= user defined % of lowest low volume over n days

I'm not sure the % limit on low volume for trade size actually will accomplish what I was attempting to explain as my concern. The % of Low Volume for maximum trade size ensures that each of us do not own an excessive number of shares of a given company (independent of the % or our account balance).... as our accounts grow and our allocations to each trade grow into (hopefully) formidable size.
The issue I was trying to identify is that with a number of strategies often selecting the same equity to purchase, there is the potential (actually happening during current simulations/trade recommendations) that regardless of account balance, three, four and (sometimes) more strategies, each with a trade allocation of say 10% for arguments sake, are recommended for purchase. Should we (or the trade processor) follow these recommendations without further risk control/restrictions we could find ourselves with 30%, 40% or 50% or our account balance tied up in a single equity.... Not quite the diversification we are attempting to create... even for the risk-takers.
Jim's note on ensuring the risk control include both recommended shares and existing positions is critical for effective risk management.

Two things..

a) There will be a setting in Account Settings that says, "Maximum of X trades per symbol" to keep it from overallocating in any given symbol. This opens up buying power for other trades, and the simulation will reflect the long-term effect of this.

b) We have roughly 100 Strategies in OmniVest now. The list will be expanded and the types of Strategies as well. My goal is to get to around 300 by the end of the year. And there will be other kinds of trading, such as in options. So the likelihood of 2+ trades on the same symbol will be greatly reduced.

Ed - I hope you will give us an opportunity to suggest which type of strategies will be prioritized in the upcoming survey. I'm sure there will be many opinions expressed but I hope for the benefit of the Nirvana Club that existing ARM strategies are added first, then uncorrelated strategies to R2M and then options trades. Of course others may want options first and ARM strategies last. But that would be sorted out by the survey.

Bob, The plan is ARM Strategies first. We already have some we have tested. It's just a matter of getting them on the servers. It's on the "short list".

IMHO there are SO MANY trades going on in so many different symbols, etc ... it's probably just a "blip" one way or t'other on the issue of partial trades when the limit is set.

I'd FAR rather see the programming time spent to permit various strategies to SCALE IN AND OUT of trades on a given symbol. But I'm sure stuff like this will come eventually ... and that it's premature now.

From this thread:
http://www.omnitrader.com/currentclients/omnivestforum/thread-view.asp?threadid=3949&posts=9



Hi Jim,

Completely agree with you that there are much more important things to be done way before partial trades which is why I said add to a future enchancement.

But it's probably important to have it sometime in the future because as your account grows, it will knock out more and more trades reducing the amount you are invested. And one of the purposes of OmniVest is to have a good portion of your account invested at all times, so your money is continually working for you.


You can see what happens from the example below:

No Volume Limit
Account grows to +$900 million and a good amount of your account is invested at all times.




0.1% Volume Limit
Account only grows to +$20 million and you are less and less invested by the end.




These are using HUGE account numbers and probably not realistic for a person to actually reach these levels. Which is why it's not important right now.
But WHEN OmniVest has all it's features and strategies added and ends up being able to produce returns like this, it would be something that's needed so your accounts don't stall.

This also goes along with ranking stratgies and adding strategies as you start maxing out your trades.

Ed, Since there is not a default setting in "Account Settings", what is a good starting "Max Trade Size as % of Avg Daily Volume" number? Is there a rule of thumb to use to get an idea of how much this number will skew the Ending Equity.

In a previous post I believe Ed said the default setting was 0.1%
I did some searching online for what would be a good setting but couldn't find too much. I did find one page that mentioned both 0.1% and 0.2%. So I'm thinking that's probably a good starting point.
