Light Node
A light node is a way of connecting to a blockchain network without storing and verifying the entire chain. A full node keeps a complete copy of the blockchain and independently checks every transaction, which takes considerable storage and bandwidth. A light node, by contrast, holds only block headers and asks full nodes for the specific pieces of data it needs, using a method often called simplified payment verification to confirm that a transaction is included without downloading the whole ledger.
The trade-off is convenience against self-reliance: light nodes are fast and can run on a phone, but they rely on full nodes for data and may depend on them to a degree for verification, depending on the implementation.
Example: A mobile crypto wallet typically may run as a light node, so a user can send and receive Bitcoin from their phone in seconds without downloading hundreds of gigabytes of blockchain history, relying instead on the wider network of full nodes to supply the required data for verification.
Lightning Network
The Lightning Network is a layer-two protocol, a system built on top of the Bitcoin blockchain, designed to make small payments faster and cheaper. Bitcoin’s main chain is secure but slow and, when busy, expensive, which makes it poorly suited to everyday transactions like buying a coffee. Lightning gets around this by letting two parties open a payment channel between them, transact back and forth off-chain as many times as they like typically near-instantly and at lower fees, and then settle only the net result on the main blockchain when they close the channel.
Channels link together into a network, so users can route payments through others without needing a direct channel to every counterparty.
Example: Two people who transact often open a Lightning channel and send dozens of tiny payments over days or weeks, each typically processed quickly, subject to channel liquidity and network conditions, and only when they finally close the channel does a single settlement transaction get recorded on the Bitcoin blockchain itself.
Limit order
An order placed at a desired price instead of at a current price.
Linear Regression Channel
A linear regression channel is a technical-analysis tool that draws the statistical line of best fit through a run of prices and then adds parallel lines above and below it to form a channel. The centre line is the linear regression itself, the straight line that minimises the distance to all the price points in the chosen period, and it represents the underlying trend stripped of noise.
The outer lines are usually set a fixed number of standard deviations away, marking how far price has typically strayed from that trend. Traders often read the channel two ways: the slope of the centre line shows the trend’s direction and strength, while touches of the outer bands suggest prices may be extended and could revert toward the centre line, although in strong trends price can stay near or move beyond a band.
Example: A trader applies a linear regression channel to an uptrending stock and, when the price runs up to the upper band, treats it as temporarily overextended, waiting for a pullback toward the centre line before considering a fresh long rather than chasing the move higher, recognising that a pullback is not guaranteed.
Liquid market
A liquid market is one where you can buy or sell quickly, in size, without moving the price around much. It is defined by depth and participation: lots of buyers and sellers, tight bid-ask spreads, and enough resting orders that a normal trade gets filled near the last price rather than slipping to a worse one. Liquidity is one of the most underrated features of a market market until it suddenly disappears.
In a liquid instrument, getting in and out is relatively low-cost and can often be executed quickly, which is why the most heavily traded FX pairs and major stock indices are heavily traded. The opposite, an illiquid market, tends to have wide spreads and prices that lurch when anyone trades meaningful size. Liquidity also tends to evaporate exactly when it is most needed, in a panic.
Example: A trader can buy ten million euros of EUR/USD, one of the world’s most liquid currency pairs, and may have limited price impact under normal market conditions, whereas the same order in a thinly traded emerging-market pair might shift the rate several pips against her before it fills.
Liquidity
Liquidity is an asset’s ease of conversion into cash without losing value, assessed by metrics like bid-ask spread and trade volume.
