Iāve adjusted the settings of the NBT sell side gateway.
Now up to 3,000 NBT are on the order book (depending on funds in the account).
As I needed to restart NuBot to activate the settings, there are at the moment 3,000 NBT on T1 from the gateway.
ALiX looks a little bit better now 
Btw. - 650 NBT have already been traded for BTC since the gateway was funded.
edit:
nud proved to be very RAM consuming (over 700 MB):
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
4013 pi 20 0 875m 694m 34m S 39.4 71.3 4069:47 nud

I run nud on the same RaPi2 on which I run the 2 NuBot instances for the Poloniex gateway function (buy side, sell side).
In total nud and 2 NuBot instances required so much RAM that the RaPi2 swapped heavily degrading performance and reducing reliability.
I stopped the NuBot of the buy side gateway as only the sell side gateway is funded at the moment. I can start the buy side gateway in very short time if need be.
As running both buy side and sell side gateway at the same time is not required/intended/recommended and the funding of the buy side with FLOT funds would likely grab my attention, I intend to keep the buy side bot shut down.
I will terminate the sell side NuBot as soon the funds (exchanged funds as well as not exchanged ones) have been withdrawn from the Poloniex account.
Current sell side gateway status is:
nud getliquiditydetails B | grep BETwD8nSjtj9ADSvej2na34xmsMYwPRymv

"1:NBTBTC:poloniex:0.3.2a_1451915895814_fb1798" : {

"buy" : 2387.5,
"sell" : 5527.3833
}
2,387 NBT have been exchanged to BTC.
5,527 NBT remain to be exchanged.
2,100 NBT of the 5,527 NBT are currently on order.
T1 buy and sell side are overall almost balanced, while Poloniex and BTER have complementary high/low buy and sell sides.
Outlook: the gateways will very soon not be āalways onā, but can be activated with short lead-time.
This will reduce the utility of the gateways as they canāt be used without manual activation (from me) after being funded by e.g. @JordanLee or @FSRT.
As only the FLOT did fund them the last times, Nu might be able to live with that.
If not, additional gateways need to be created.
edit2:
both Poloniex gateways are on standby (and no longer always on) after round five of the NBT entry gateway has been completed exchange wise (withdrawal will take another 24 hours).
