Yesterday I wanted to buy 100,000 units of some coin at the last rate in the exchange because I wanted it urgently. However, I could only get 18,000 units on the spot. More than 24 hrs later, my order is yet to be filled. Meanwhile the coin has gone up 400%. How frustrating! Now my question is...

1. Will the remaining order be filled at the old rate or the new rate?
2. Do all the exchanges operate like this?
3. Are there exchanges where you get your order filled instantly knowing that time is money?

Many thanks.

Can you tell me where are you doing that ?
it is Market Order or Limit Order ?
there are a lot of missing details about your trade,do you understand what is Market Order and Limit Order right ?
it's not about slow in filling your orders but instead about your orders,
if you bought it using Market Order,you should get it in no time.which mean when you use it you will get your coin in the next second aka buy instantly.
how about Limit Order ? it's an order where you put your Buy/Sell to the place that you want to Buy/Sell.
you will get it/sell it whenever someone fill your orders.

 Obviously when you tried to buy at the "last rate" there wasn't sufficient volume to complete your trade.  Now that the new rate is up 400%, your unfinished order will languish until the value comes back down to the "last rate" whatever than was.  You'd be wise to cancel your order now to free up your funds for new orders and congratulate yourself on quadrupling the value of the 18k coins you purchased.

These two coins fit your explanation of the increase of ~400% in one day and as you can see, the exchange volume was too low to execute your trade.  You need to pay attention as it is likely that your actions caused the large increase in value;  not a smart way to accumulate low-value coins unless you are ready to go looooooong.

Let me know the name of that exchange and tell me whether you have placed an Limit order or Market order. Meanwhile i will tell you some key points  for your questions.

1 ) Note that Your remaining order will get filled according to the current market price and not previous one, because if it has not get filled previously
    that means there were no enough volume or participation in that coin at that time and it will get fill once you get your ordered number of quantity
     over there.

2) & 3)
    No Every exchange dont operate like this, always go for Traditional Exchange like Bitstamp, GDAX other than OTC exchanges where your order
    doesn't gets filled soon and if you are going for brokers then go for brokers having ECN platform (electronic communication network)or something
    which is working good like Bitfinex, Coinbase, Bittrex, and Bitstamp they are good and reputed one's with almost zero lag & less slippage of orders.

Yes I agree to you that there isn't sufficient volume to complete the trade because sometimes the popularity become low that can cause to hold some coins and wait to be pump when they become popular and the volume is huge. Some people want to dump the coins for their own needs but some also don't want that results sometimes an unfulfilled orders.

Maybe exchanges slow in filing orders because of not implenting the segwit2x hardfork to the system, due to some circumstances,thats why they postponed the implementation of segwit2x this coming 2nd week of month.as far as we know segwit system is created to wide the pathway of every block,and divided the headed part to the body part,to give way the transaction smooth flows and wide with no interference.segwit2x was created to make the exchange  fast transaction in the world of digital currency.

Exchanges are not the one's buying and selling their coin. People were the one that are selling and buying. That is why, and by that, it is up to the person if they wanted to buy coins or sell their coins. That is why there is a slow movement.

Trading Tip

If you are on a highly volatile market and beleive price will go high, just your coin from the lowest rates available and you dont need to place a trade order

For you to know orders are not controlled by the exchangers so dont blame them they are just a platform for trading it only happened that your order did not filled because price went up and seller sold it in a more high price than your buying order so it must be filled when prices you order are meet with the sellers price. 

all true but in other words the real reason why your order was not filled is because you went against the market!

you say the coin has gone up 400%, that means you were placing low bids on a market that was rising when you should have either bought on the rise meaning placed a market order and bought at the higher ask price or you should have placed your order like you already did and kept increasing it each time it failed to be filled until it is filled completely.
i personally prefer the fist option, to buy at market price. when you see the pump going on you should jump on board as fast as you can, not wait for the orders to be filled below market price, you do that when pump is not yet started.
