Yeah apparently they are VERY confused. I will copy them on this interchange. Only question which remains is how to deal with lack of synergy between listed spreads and underlying outrights. I execute using the spread book - Sierra says I’ve got a spread margined correctly at X, clearer shows I have an equal number of long and short outrights which is customary but from what they are saying those will just be margined as sum of outrights which of course defeats the whole purpose unless they have a workaround for that. Example same as above. Say I’m running risk at 1 lot per 5k and I’ve got 3 spreads on. Sierra says correctly my risk is $900. Clearer sums those outrights and says my overnight risk is $4500 plus or whatever and liquidates me… If I might, can I make a suggestion to eliminate these conflicts? If Sierra is able to derive correct SPAN values for spreads when those symbols are used, why not just use that very same info to show the position in Sierra as the customary long and short outrights just as the clearers will, and deriving the correct overnight margin from the same info? This would also simply solve the issue of not being able to exit/enter spreads synergistically via outrights or spread books and not have biggest problem for spreaders being Sierra still thinking say you’re still long or short a spread when in fact the position with the clearer is actually flat because you’ve legged out of it. I’m no developer but it seems like this should be a very easy fix which removes these conflicts for spreaders. Thanks again for your consideration. |
