Question about volume

[dexterrockypuppy]

Hi,

When looking at alt cloins, particularly on smaller exchanges such as Yobit, it seems a very small amount of volume can move a price quite dramatically.I was just wondering if the volume within a particular candle is the actual value of matched orders or just orders that have been placed?

Also say a coin changes from 100 sat to 300 sat then back down to 200 sat all within the same candlestick on a chart. How is the btc volume figure worked out, with the alt coins value changing all the time?

Thanks.

don't look at yobit much, it is very unreliable. i can even say all the numbers on there are a lie.

it seems a very small amount of volume can move a price quite dramatically.

this is because this market is still small, specially when it comes to altcoins and the small altcoins. there is so little demand. and consequently it becomes very easy to manipulate it.

the volume in a candle is the order that was filled.
lets say the sell orderbook is like this:
price(BTC)-------- volume
0.010-------- 100
0.011-------- 40
0.012-------- 200
if all these 3 gets filled price rises to 0.012BTC and the total volume is 340 unit of that altcoin equal to 3.84BTC which is the total of orders filled (0.010 * 100 + 0.011 * 40 + 0.012 * 200)
