JBL Risk ManagerPosition sizing is your first line of defence against catastrophic loss.
Most traders decide what to buy. Far fewer decide what being wrong is allowed to cost them. JBL Risk Manager answers the second question first — how much to buy, where the exit sits, and exactly how many dollars are on the line — before you place the trade.

Risk Management is vital to Trading Success — and Position Sizing is the missing key to successful Risk Management.
It is regarded by successful traders to be one of the most important components of any Trading Plan.
When you combine intelligent Position Sizing with effective Risk Management and use a Stop Loss, you are planning for your long term trading and/or investment success.
What risk management actually means
Four questions, in the order a trade meets them. Answer them before you enter and the trade is a calculated risk. Answer them afterwards and it is a guess.
“How much can I buy?”
Position sizing
Not a round number, and not simply what you can afford. The size is worked out from your capital and then held down so that being wrong costs you no more than your limit allows. This is the discipline the product is named for.
Trade Form →“Where do I get out?”
The stop loss
Decided before you enter, not in the moment you are losing money. The app places a stop that accounts for how much the stock normally moves, so ordinary noise does not shake you out — and you can override it with your own technical level whenever you have one in mind.
Trade Form →“What does being wrong cost?”
Capital at risk
The actual money on the line if the stop is hit — the number most traders never work out. This is what the model caps. Position size is what you spend; capital at risk is what you can lose, and only the second one can damage the account.
Capital Management →“Is any of this working?”
Expectancy and R
Every closed trade is measured against what you risked on it. Those measurements roll up into expectancy, system quality and drawdown, which answer a question a profit figure cannot: is this system sound, or did one lucky trade carry the year?
Trading Summary →The limit is set by your account, not your mood
One trade should never be able to do serious damage. So the model caps what any single trade is allowed to cost you, as a share of your capital — and it tightens that cap as the account grows, because a larger account has more to protect and does not need to risk as much of it to make progress.
Every position size in the app is worked backwards from that limit. You are never asked to remember it, calculate it, or enforce it yourself — which is the point, because it is precisely the rule that gets abandoned in the moment it matters most.
Remove emotion and guesswork from your trading decisions.
Without a risk model, four decisions get made by instinct, usually at the worst possible moment:
- Position size chosen as a round number, or as whatever cash was spare.
- The exit decided while the trade is already losing money.
- No idea what a single trade going wrong actually costs the account.
- A year judged on its profit, with no way to tell skill from one lucky trade.
An easy to understand portfolio management system: a simple trading plan you will understand, based on your own risk tolerance.
How it works
Three steps, no finance degree required.
Set your capital and your rules
Create a portfolio with its starting capital. That figure sets your risk limit, and the brokerage and ATR settings behind every calculation.
Size the trade before you take it
Enter the symbol and your intended buy price. Back come the stop, the quantity, and the exact dollars at risk — while it is still a decision, not a position.
Let the closed trades report back
Record each exit. R-multiples, trade expectancy, SQN and drawdown accumulate into an honest read on whether your plan works.
Shares across 16 exchanges in 4 regions, with price data included. Each portfolio sets its own market, and the currency follows it.
What the JBL Score is — and isn't
Alongside the risk model, the app gives every stock a single 0–100 JBL Score to help you shortlist. It weighs a stock's trend, its volatility, what it costs relative to what it earns, and the strength of its balance sheet.
How those are balanced against each other is our judgment about what matters most for a first read on a stock — it has not been backtested against historical returns. The score describes the present, not the future: it does not predict performance, and it is not investment advice. The risk model is what protects your capital; the score only suggests where to look.
