The Zeniteri platform: three views, one routine
A tour of the depth ladder, the risk ruler and the recovery curve: what each shows, what you can control, and where its limits are.
What the platform is for
Zeniteri is a market workspace for reading depth, sizing risk and understanding recovery. It exists for a particular kind of user: someone who wants to understand the conditions around a trade and the consequences of sizing it, rather than someone who wants to be told what to do.
That focus shapes the design. Each view answers one question and answers it clearly. You can read one in a minute, use all three in a sitting, and leave without having been nudged toward anything.
The three views at a glance
- Depth ladder. Where size is resting either side of the spread.
- Risk ruler. The position size that matches a risk budget you set.
- Recovery curve. The gain a loss demands before you are back to even.
The boundaries are stated beside each view, and gathered together under data and limits.
View one
The depth ladder
What you see. A column of prices with the spread marked at the centre. Buy interest is drawn as bars growing leftward below the spread; sell interest grows rightward above it. The longest bar in view is easy to spot, and so is a gap where nothing is resting.
What it lets you do. Judge how much weight a price level deserves. A level with deep size behind it is harder to move through than one with a sliver. You can also gauge the spread, which is the cost of getting in and straight back out.
A use case. You are thinking of entering near a round number. The ladder shows plenty of sell-side size sitting just above it. That does not mean the price will stall, but it is a reason to place your stop with care and to size with the risk ruler rather than by instinct.
The limit. Resting size can be pulled in an instant, so the ladder describes a moment, not a promise. The version here uses invented numbers so that you can learn the layout without mistaking it for the market.
Illustrative depth ladder. Invented numbers, not live data, not a prediction.
View two
The risk ruler
Turn a risk budget into a position size, the same way every time.
What you see. A short set of inputs and four results: the money at risk, the distance from entry to stop, the size that fits, and the direction your stop implies.
What it lets you do. Decide the loss you are willing to accept first, and work the size out from it, rather than choosing a size and discovering the loss afterwards. Change the stop and watch the size respond; change the budget and see the whole position scale.
A use case. You have two ideas with the same entry but different stops, one tight and one wide. Run both. The wide-stop idea produces a much smaller position for the same budget, which tells you what that idea really costs to hold.
The assumptions. The calculation is: money at risk equals balance multiplied by the risk percentage; position size equals money at risk divided by stop distance multiplied by the multiplier. It assumes your stop fills at the price you set. It excludes spread, slippage, commission, financing charges, currency conversion and gaps.
The multiplier. This is the money value of a one-unit price move for one unit of your instrument. A generic lot size would be misleading here, because contract sizes differ from one instrument to the next, so the calculator asks for the figure rather than assuming it.
A European example. Suppose a share listed on a European exchange trades at €50.00 and you decide the idea is wrong below €48.50. With a balance of €10,000 and a 1% budget (€100), the ruler returns about 66.67 shares, because each share loses €1.50 if the stop fills. The numbers are illustrative. Exchange sessions and holidays are set by each venue; see Euronext's calendar for the Paris market.

The recovery curve
See how the climb back steepens as losses deepen.
What you see. Loss along the bottom, the gain needed to recover up the side. The line starts almost flat and then rises sharply, which is the whole lesson in a single shape.
What it lets you do. Set a loss with the slider and read the exact gain needed in large type. Use it to think about drawdown limits, or simply to feel why protecting capital matters more than it first appears.
A use case. You are deciding where to place a daily loss limit. At 5% the climb back is 5.3%. At 25% it is 33.3%. Seeing the two side by side makes the case for a tighter limit better than any rule of thumb could.
The assumption. The curve uses gain = 100 × loss ÷ (100 − loss), valid for any loss below 100%. It assumes the same balance carries through, with no deposits, withdrawals, fees or taxes. It does not suggest that recovery is probable.
The limit. A mathematical route back is not the same as a likely one. Treat the curve as a reason for caution, not as a target to aim at.

What you see and control
Each view, side by side
A summary of the information each view gives you, the controls you have, and what it leaves out.
| View | Information shown | Your controls | What it does not do |
|---|---|---|---|
| Depth ladder | Price levels, size resting on each side, the spread and the top of the range in view | Reading only on this site; the version here is a fixed illustration | Show live prices, predict direction or place orders |
| Risk ruler | Money at risk, stop distance, position size, implied direction | Balance, risk percentage, entry, stop, multiplier, optional currency label | Include costs, guarantee a stop fills, or choose a risk budget for you |
| Recovery curve | Gain needed to return to your starting balance after any loss from 1% to 90% | A slider for the loss percentage | Estimate how likely recovery is, or include fees and taxes |
Plain-English glossary
Terms used on this site
You do not need prior trading knowledge to follow these pages. Here are the words that matter, in the order you will meet them.
- Spread
- The gap between the best price someone will pay to buy (the bid) and the lowest price someone will accept to sell (the ask or offer). Crossing it is a cost of trading.
- Order book and depth
- The list of buy and sell interest waiting at each price. Depth means how much size is waiting.
- Stop price
- The price at which you decide an idea has failed and you plan to exit. It sets how far a trade can move against you before you act.
- Position size
- How many units of an instrument you hold. A larger size multiplies both gains and losses.
- Multiplier
- The money value of a one-unit price move for one unit of the instrument.
- Drawdown
- The fall in your balance from a previous high, often shown as a percentage.
- Slippage
- The difference between the price you expected and the price you actually got, common in fast markets.
Using them together
A walkthrough of one idea
Read the ladder
You notice the spread is narrow and the buy side is consistently deeper for the five levels below it. You note it as context, not as a signal.
Decide where you would be wrong
You choose a stop beneath the nearest level that looks well supported, and an entry that keeps the distance sensible.
Size it with the ruler
With a 1% budget the ruler returns a position. It is smaller than you had in mind, so you leave the stop where it is and accept the smaller size.
Check the downside against the curve
You set the slider to your daily loss limit and see the gain it would demand. The number is modest, so you proceed. Had it been uncomfortable, the limit would have been the thing to change.
Access, data and limits
What to expect and what not to assume
Devices and access. This website is designed to work on phones, tablets and desktops. Device, browser and access requirements for the workspace itself will be confirmed when access is arranged, so none are promised here.
Data. The calculator and the recovery curve compute only from the figures you type, in your own browser. The ladder uses invented numbers. The only live prices on this site are in the strip under the header, supplied by TradingView; the views described here do not use them. This site shows no other live prices, research or news, and the workspace does not hold money or place orders in these views.
Automation and integration. The views described here do not trade on your behalf, and they are not connected to a broker account. Registering your interest may lead to an introduction to an executing broker, which is a separate firm with its own terms.
Not advice. Nothing here is a personal recommendation or a view on any instrument. Whether any approach is suitable depends on your circumstances, and trading carries a high risk of loss.
Platform questions
About the views and their limits
Which of the three views can I try now?
The risk ruler and the recovery curve are working tools on this page: type in figures and they calculate. The depth ladder is an illustration with invented numbers, shown so you can see the layout and learn to read it.
Can I place orders from these views?
No. The views are for reading depth, sizing risk and understanding recovery. Nothing on this page places, routes or confirms an order.
When are European markets open?
Each exchange sets its own sessions and holidays. Euronext, which runs the Paris market, publishes a calendar of days its cash markets are closed; outside those days they are open Monday to Friday. Check the exchange's own calendar for session times, and remember that a broker may offer different hours for its own products.
Where does the ladder get its prices?
It does not get them from anywhere: the numbers are invented for illustration. Any market data connection for the workspace itself is not described here until it has been confirmed.
What is the multiplier in the calculator?
It is the money value of a one-unit price move for one unit of the instrument you are looking at. For a share quoted in euros, one share gains or loses €1.00 for each €1.00 move, so the multiplier is 1. Other instruments differ, so check the contract specification with your provider.
Why does the calculator not include fees?
Fees, spreads and slippage vary by provider and instrument, and any figure typed in here would be a guess. The result is therefore a ceiling on the loss from the price move alone, before costs and before any gap through your stop.
Does the workspace save my layouts or watchlists?
No saved layouts, watchlists or accounts are described on this site, so none should be assumed. Anything of that kind will be listed on this page once it exists.
