How to do multiple open orders with "First come first serve" principle

[beaupain]

Hey

Imagine I have $1000 and I want to take multiple open positions in various coins, all worth my full available budget ($1000 in this case).  Today I cannot do this, as the system already reserves your budget to take an open position.

Isnt there a way to setup my exchange (Bitfinex in my case) so that the first open order which is being materialized takes all the budget ($1000) and the other open orders are automatically deleted?  "First come, first served" principle

Example:   $1000 open orders on:

1) BTC <10K$
2) LTC <0.1K$
3) XRP <0.2$

At a certain point, LTC drops below 0.1K$ (before the other 2 conditions, BTC and XRP in this case, happen) => order is being processed for the full $1000, the rest is cancelled (as no budget left anymore).


Thanks!

I don't think this is possible for the exchange: different order pairs run separate from each other. If they would set it up like this, I think (read: this is based on my current understanding, although I'm not entirely sure) it could be possible both orders are triggered at exactly the same time, and you end up $1000 negative.
