Transaction Expiration for Lindex

I've been watching the Lindex for the last few months and while I realize the movement on the Lindex is governed by many different factors I see one particular area that to my completely untrained eye could be improved. Before I try submitting the idea however I figured it might be a good idea to ask out here if this idea has any consequences that just aren't occuring to me in my financial noobitude.

Proposal: Transaction Expiration for Lindex Sell Orders

Problem (as I see it): For whatever combination of reasons (unfamiliarity with the system, too much currency in the market, market manipulation, laziness, impatience, plain old bad luck, etc.) it seems that over time semi-permanent "barriers" have been erected in the form of blocks of millions of L$ sitting at various positions on the Lindex ($266, $265, $261, $251, etc.). Each time the value of the L$ approaches one of these barriers the price inches back down because sellers do not want to have to wait for buyers to chew through the $2+ million L$ already sitting at that level. In watching the barrier blocks I see that they do not disspiate over time as one might expect - whoever is contributing to these blocks just leaves the cash there rather than choosing a better position. Over time this appears to have created levels above which the L$ price will just plain not realistically climb... and these barriers keep cropping up further and further down the line. It would seem to me that this artificially impedes the natural supply/demand movement of the L$ price and could be very easily manipulated buy those with a little extra cash and a little patience.

Idea: Set a term for sell orders - if your $50,000L block hasn't sold in a certain amount of time (7 days? maybe?) then the order is cancelled and the cash reverts back to your account. This would apply to all sell orders regardless of amount.

The hope is that this expiration would help prevent the barriers from forming, or at the very least make it more difficult for them to stick around, giving the L$ price some breathing room to move with demand. Is there really any good to be had from leaving this cash stagnant in the Lindex system?

So... does this make any sense, or have I forgotten to consider some glaringly obvious horrible consequence? Your help is appreciated!

It's a nice thought, but whether the orders expire or not, the Lindens still need to be sold.

The barriers are real. You can't expire them away. At least, I don't see how.

Just oops the blocked $L into oblivion.

Speaking as someone who is sitting at one of those blocks; that is the better position for me. I am perfectly willing to wait as long as it takes for them to sell and I would very much prefer to not have to relist them just because you would rather I not be sitting there.

They are not forgotten and I check on them weekly to confirm they are not anywhere near being close to the current value.

I think you will also find that those blocks do sell every once in a while but more piles onto the end of the queue when that happens so you are unlikely to notice.

Well, what you're ignoring is that fact that these "blocking" orders are in fact part of the market dynamics and the market *is* moving with demand. It's just that right now, there is far more supply (as evidenced both by people like prak that can leave their L$ parked at a certain price for months, and by the downward trend in the exchange rate) than demand. If no more currency were listed for sale (i.e. supply dried up), you would eventually see the price creep up through the blocking orders.

Automatically de-listing orders would just make the market less predictable.

Very true and well said.

The fact is that we should be thankful that those people are willing to wait. If they were trying to sell right away, then the market would be in much worse trouble than it currently is.

Why not just delete any $L left in Lindex over 30 days?
