The position size calculator Sierra Chart never had.
Place an entry, a stop and a target on the chart. Contracts, dollar risk and reward-to-risk update as you move them. It anchors to the candle, so it stays put while the market keeps printing.
Standard · one target, one mode. You set stop, target, size · It solves risk and reward in money
Try it here first: the chart on this page is a working copy of the tool. Click a handle to pick it up and every figure follows your pointer; click again to set it down.

What makes it different
Built by a trader who was tired of doing this by hand.
Sierra Chart's Reward/Risk tool tells you what a quantity risks. It never told you the quantity. This one does, and it was made to feel like part of the platform, then checked line by line.
Anchored to the candle, not to the screen
Most chart drawings drift as new bars print. This one is pinned to the candle you place it on, so the box on your entry candle stays there and becomes a record of the trade.
Handles, not lines
Thin lines are a poor click target on a busy chart. Each level gets a triangle you can grab, so you never fight the chart for a line.
Works on anything the chart can show
Only two chart values are read: Tick Size and Currency Value Per Tick, both with overrides. Negative prices, spreads and back-adjusted contracts included. Time, tick, volume, range and Renko bars.
Reward-to-risk after commission
Enter your round-turn commission per contract. Risk includes it, reward subtracts it, and the ratio is taken from the money, not the raw ticks.
X hides. It does not forget.
Size, direction, distances and box width are all kept. Right-click and it comes back exactly as you left it.
Sits ahead of the market
Move it into the empty space right of the last candle for a level you are waiting on. The width handle works out there too.

FAQ
Straight answers, the way a trader asks.
Does Sierra Chart have a position size calculator built in?
Not a position size calculator, no. Sierra Chart has a Reward/Risk drawing tool, but it works the other way round: you give it a quantity and it tells you what that quantity risks. Sizing from a risk budget, which is the calculation you actually need before the trade, is the part Sierra Chart's own engineering team called 'not directly supported', so it means a spreadsheet or mental arithmetic while the market moves. PSC is a custom study (Sierra Chart's word for an indicator) that puts that calculation on the chart: entry, stop and targets as a box you can move, with contracts, dollar risk and reward-to-risk on the labels.
Is this like TradingView's Long Position and Short Position tools?
Yes, that is the model, with what a Sierra Chart trader needs on top: sizing in contracts, dollar risk from the chart's own tick value, commission in the ratio, and a box that stays pinned to its candle. Pro adds a mode that works out the contract count from your risk amount, and up to three targets.
Which Sierra Chart version do I need?
Sierra Chart 2941 or later, 64-bit, on Windows. Help › About shows your version; if yours is older, Help › Download Current Version updates it for free in a couple of minutes. Built and tested on 2947. One file, nothing else to install.
Which instruments does it work on?
Any symbol the chart can show: index futures such as ES, MES, NQ and MNQ, energies and metals such as CL and GC, currencies, bonds, stocks and forex. Only two chart values are read, Tick Size and Currency Value Per Tick. Negative prices work (spreads, back-adjusted contracts), and so do time, tick, volume, range and Renko bars.
The dollar figures look ten times too big. Why?
Your chart's Currency Value Per Tick belongs to a different contract, usually the full-size when you trade the micro. Fix it under Chart Settings › Symbol, or set the study's own override input.
What is the difference between Standard and Pro?
Same engine, same drawing. Standard has one target and one sizing mode: you set the size and it tells you the risk and reward. Pro adds Auto Size, up to three targets with weighted shares, and the over-budget warnings. Pro also includes the Standard study in the same download, so you can run the simpler one on some charts. The table above lists every difference.
What are the known limits?
Five, all stated before you buy. The on-chart buttons and the grab handles only respond while Sierra Chart's Pointer, Chart Values or Hand tool is selected; that is a platform rule, and the right-click menu is unaffected. Reward-to-risk assumes every target fills and does not model moving the stop to breakeven after a partial exit. The two editions are built to share a chart; two copies of the same edition are not. One box is meant to be moved and reused, not left behind. A second copy can be forced with a drawing line-number base at least 180 apart, but both copies start in the same place and answer the same click, so separate them before you drag. The box is pinned to its bar on every chart type, but a label sitting right of the last candle has no bar to pin to, so it is placed from a projected bar spacing and can sit slightly off on tick, volume, range and Renko charts. Equal label widths assume a monospaced font such as the default, Consolas.
How do I get the file after paying?
Immediately. The page after checkout has the download button, and the same link is emailed to you. The download is a ZIP holding the DLL (the study file), a short readme and a licence registered to your order. Unzip it, copy the DLL into your Sierra Chart Data folder with Sierra Chart closed, start it, and add the study from the Studies list.
Where is the manual?
The setup guide is public. The full reference, with every setting, formula and label format, comes with your purchase: it is linked in your order email and on the confirmation page. If you lose the link, the recovery page sends a new one.
What if I lose the download link?
Use the recovery page. Enter the email you paid with and a fresh link is sent to that address.
Can I use it on more than one computer?
Yes, on the machines you personally trade from. The licence is for one trader. Sharing, reselling or redistributing the file is not allowed.
Do I get updates?
Yes. Bug fixes and updates to the edition you bought are free; a fresh download link is sent to the email you paid with.
Is there a trial or a refund?
Neither. It is a digital download delivered instantly, so there are no refunds; that is why the setup guide and this FAQ, limits included, are public before you buy. If the study will not load on a supported Sierra Chart install, contact support and we will get it working. Payment runs through Stripe's Link, which has its own consumer rules and may refund within 60 days in specific cases.
Why does the checkout add tax?
Stripe acts as the seller of record and adds the sales tax, VAT or GST your billing address requires, then remits it to the tax authority. The price on this page is before tax. Your card statement will show LINK.COM* followed by our name.
Is there any licence key, login or phoning home?
No. The DLL runs offline. Nothing is sent anywhere.
