SmartEvery forex concept worth understanding – risk, position sizing, the cost of a trade – sits on top of three plain units: the pip, the lot, and leverage. Get them straight and the rest of the market starts to make sense; leave them fuzzy and you are trading blind, usually with far more money on the line than you realise. This is the foundational explainer: what a pip really is, how lots turn pips into dollars, and why leverage is both the reason forex is accessible and the reason so many accounts do not survive their first year.
The Pip: Forex’s Basic Unit of Movement
What a Pip Actually Is
Before any of the bigger ideas make sense, you need the pip. A pip is the standard unit of price movement in a currency pair – for most pairs, including NZD/USD, it is a change in the fourth decimal place. If NZD/USD moves from 0.6000 to 0.6001, that is one pip. From 0.6000 to 0.6050 is fifty pips.
The pip exists because currency moves are small in percentage terms but happen in large size, so the market needs a consistent way to talk about them. When a trader says the Kiwi “dropped forty pips after the data,” they are describing the size of the move precisely, without reference to how much money anyone made or lost on it. That distinction – between the size of a move and its value to you – is the thread running through this entire article, so hold onto it. The pip is the basic unit of nearly every conversation in forex.
Pipettes and the Fifth Decimal
Look at a modern trading platform and you will usually see one more digit than you expected: NZD/USD quoted as 0.60012 rather than 0.6001. That fifth decimal is a pipette, or fractional pip – one tenth of a pip. Brokers began quoting it to compete on finer pricing and tighter spreads.
It is a small thing, but worth recognising so the extra digit does not confuse you. When you are reading a price or setting an order, the second-to-last digit is your whole pip and the final digit is the pipette. Nothing about the concept changes; the platform is simply giving you more precision than the pip alone. Most of the time you will think and plan in whole pips, and treat the pipette as rounding.
A Pip Is Not a Dollar
Here is the mistake that trips up almost everyone early on: assuming a pip is worth a fixed amount of money. It is not. A pip is a movement in price, and what that movement is worth to you depends entirely on how large a position you are holding. The same forty-pip move might be worth four dollars to one trader and four hundred to another, trading the identical pair at the identical time.
This is why you cannot talk about risk in pips alone. “I’ll risk thirty pips” means nothing until you also know the size of the position behind those pips. To turn pips into dollars – which is what actually matters for your account – we need the next building block: the lot.
Lots: How Much You Are Actually Trading
Standard, Mini and Micro Lots
A lot is simply the quantity of currency you are trading, and it comes in standard sizes. A standard lot is 100,000 units of the base currency – for NZD/USD, that is 100,000 New Zealand dollars. A mini lot is 10,000 units, and a micro lot is 1,000 units. Many brokers now also offer nano lots below that.
These tiers exist so that traders with very different account sizes can take sensibly scaled positions. A fund desk might trade dozens of standard lots; someone starting out with a modest account has no business doing the same. The lot size you choose is one of the most important risk decisions you make, even though it looks like a purely mechanical input box on the platform. Smaller lots are not a sign of timidity – they are how a small account stays alive long enough to learn.
What a Pip Is Worth Per Lot
Now we can join the two ideas. Because NZD/USD is quoted with the US dollar as the second currency, the pip value works out cleanly in US dollars. On a standard lot of 100,000, one pip (0.0001) is worth about ten US dollars. On a mini lot it is about one dollar, and on a micro lot about ten cents.
So that forty-pip move from earlier is worth roughly four hundred US dollars on a standard lot, forty on a mini, and four on a micro – the same price move, three very different outcomes. Suddenly “a pip is not a dollar” becomes concrete. When you plan a trade, you work backwards from the money: how many dollars am I willing to lose, how many pips away is my stop, and therefore what lot size keeps those two figures in line. That calculation is the heart of position sizing, and it depends entirely on knowing your pip value per lot.
Choosing a Lot Size That Fits Your Account
The practical upshot is that lot size should follow from your account size and your risk tolerance, not from ambition. A trader with a few thousand dollars who opens a standard-lot position is exposing themselves to roughly ten dollars of swing per pip – a fifty-pip move, easily seen in a single session around a data release, is five hundred dollars. On a small account, that is the difference between a routine loss and a serious dent.
This is exactly why micro and mini lots exist, and why experienced traders often use them deliberately rather than treating them as training wheels to be discarded. The goal is to size positions so that a normal losing trade is survivable and unremarkable. Get the lot size wrong and even a correct view of the market can ruin you, because you were never going to survive the drawdown along the way. Which brings us to the tool that makes oversized positions possible in the first place: leverage.
Leverage and Margin: The Double-Edged Tool
What Leverage and Margin Mean
Leverage lets you control a position far larger than the cash in your account. Expressed as a ratio – 30:1, 100:1, and so on – it tells you how many dollars of position each dollar of your capital can control. At 100:1, a thousand dollars controls a hundred thousand: one standard lot. Margin is the flip side of the same coin – the deposit your broker sets aside as collateral to hold that leveraged position open.
Leverage is genuinely useful; it is what makes forex accessible to people without institutional capital. But it is also, by a wide margin, the single feature most responsible for traders losing their money quickly. The reason is simple arithmetic, and it is worth seeing laid out plainly, because the marketing around leverage almost never shows you this side of it.
A Worked Example: How a Small Move Wipes Thin Margin
Take a thousand-dollar account using 100:1 leverage to hold one standard lot of NZD/USD. We know one pip on a standard lot is worth about ten US dollars. Your entire thousand-dollar account, then, is roughly a hundred pips of room. NZD/USD can move a hundred pips on an ordinary day with an RBNZ decision or a US inflation print.
In other words, a price move of about one percent – against you – is enough to wipe the account out entirely. Leverage did not just magnify a gain you were hoping for; it magnified the loss to the point of being terminal. This is the mechanism behind the uncomfortable statistic that most retail forex accounts lose money. It is not that the traders were always wrong about direction; many were simply leveraged so heavily that normal market noise closed them out before any view could play out. Leverage magnifies losses exactly as efficiently as it magnifies gains – and losses are what end accounts.
Leverage in New Zealand, and Using It Sanely
New Zealand traders can access relatively high leverage compared with some jurisdictions, as the Financial Markets Authority licenses derivatives providers but has not imposed the hard retail leverage caps seen in Australia or Europe. That makes the responsibility to use leverage sensibly fall more heavily on you. The available leverage is a ceiling, not a target.
The traders who last tend to use a small fraction of the leverage on offer, sizing positions off their stop-loss and risk-per-trade rather than off how large a position the margin will technically allow. Used that way, leverage is a convenience that frees up capital. Used as the marketing implies – to maximise position size and chase outsized returns – it is the fastest route to a blown account. Forex trading carries a real risk of loss, and leverage is the dial that decides how fast that risk arrives. Turn it down.
Pips measure the move, lots turn that move into money, and leverage decides how violently both land on your account. None of it is complicated, but the order matters: you size a position from the money you are willing to lose, not from the position your margin will allow. The traders who treat leverage as a ceiling to stay well under, rather than a target to reach, are the ones still trading a year later. The units are simple. The discipline of respecting them is the whole game.
