Fictional example, for illustration.
Winning often doesn't mean keeping your profits.
You can win 6 trades out of 10 and still watch the market take back a big part of your profits before you exit. Here is what LossLens brings to light, on a sample of 15 trades.

Profits given back to the market
−$2,140
On 6 trades, profit had climbed higher before you exited. That gap is what the market took back.
The 6 trades in question
A trade can climb, then fall back before you exit. The gap between the peak and your exit is the profit the market took back. LossLens measures it.

Free calculator
How much does the market take back from you?
Four sliders, ten seconds. You get a first estimate. The free analysis then measures the real number, on your real trades.
An estimate based on your answers, not a promise. Your real number depends on your trades: that's exactly what the free analysis measures.
What LossLens reads
Where your money goes, and why.
LossLens reads every trade on the chart, with clear rules: structure, zones, liquidity, stop, size and state of mind. You have nothing to tag.
01
Unbanked profits
How LossLens spots it
The trade reached at least +1 R (your own risk) in your favour, then you exited with less than half of that gain.
Why it's expensive
You were right about the direction, and the market still took the money back. Your journal shows a win; it doesn't show what you left behind.
Sample rule for tomorrowBank half of your position at the first level, then move your stop (SL) to your entry price.
Threshold adjustable in your settings.
What you get, for free.
You send your MT4 or MT5 trade history. LossLens sends back your 3 most expensive mistakes, priced in dollars, and one simple rule to apply from your next session. No credit card.
Read-only: we never ask for your trading password.

What works for you
Your results by entry type. Not generic advice: yours. (Sample data.)
The news × your trades soon
Every morning, a summary of the economic news: which pairs lean up or down, and which hours to avoid. In the evening, you see whether you traded with the market or against it.
A rule, not a spreadsheet
Every trade review ends with one or two concrete rules for your next session. The kind of sentence you read again before opening MT5.
How it works
Three steps. You only do one.
01 · you
You connect MT4 or MT5
A small program (expert advisor) sends your closed trades to LossLens, with your stop (SL), your target (TP) and the chart. Or you simply send your history.

FAQ
Before you sign up.
Which platforms does it work with?
MetaTrader 4 and MetaTrader 5, with a personal account or a prop firm account, at any broker. cTrader later, if there is demand.
Do I have to fill in tags after each trade?
No. Tagging is automatic. You can correct a tag if you disagree.
Do you get access to my account?
No. LossLens only reads your trade history. It can't open or close positions and never asks for your trading password.
Is it a signals service?
No. LossLens analyses what you have already done. It is not investment advice: your decisions stay yours.
Where is my data kept?
App data is hosted in Switzerland (Zurich), a country the European Union recognises as protecting data to its own standard. You can delete your trades whenever you want. They are never sold.
Can I cancel whenever I want?
Yes, in two clicks from your account, with no call or email.
I already have a journal or a spreadsheet. Why switch?
A journal counts your trades and asks you to tag them. LossLens spots your mistakes on its own and tells you what each one cost you, in dollars. You can keep your spreadsheet alongside if you like.
Does it work with my prop firm?
Yes, if your account runs on MetaTrader 4 or 5. You enter your prop firm's limits (daily loss, max loss) and LossLens shows you where you stand. It never guesses your rules for you.
How does the free analysis work?
You sign up with your email. When the analysis opens, you get a link to send your MT4 / MT5 history. LossLens sends back your 3 most expensive mistakes, priced in dollars, and one rule to apply. No credit card.
When does it launch?
LossLens is in private beta. People on the list go first, in small groups. You get an email as soon as it's your turn.

LossLens
Tells you why.
Why I built LossLens
Four years in the markets taught me one thing: you learn the theory fast, but the psychology follows you for life.
A few days of profit, then one bad day is enough to undo it all. Burned profits, blown accounts: I went through that cycle too often, without being able to name what set it off.
I'm not alone. Many traders go through the same thing without understanding why. Most journals stop at statistics: win rate, P&L, max drawdown. They tell you what happened, never why.
LossLens starts from the other end. It reads every trade, spots the behaviour behind the mistake (a revenge trade, a bad time to enter, a news release) and tells you what it cost you. Understanding the root of a mistake is the first step to never making it again.
