Black Diamond EA Review: What the Numbers Actually Show

Last updated: September 1, 2026 · By: Tim Morris

Black Diamond EA is sold via Telegram in three price tiers, and the sales page claims up to 95% accuracy and 80 to 120% monthly returns. None of that is backed by a verified real-money track record. Its set files also carry an optional martingale that contradicts the low-risk, fixed-lot branding, the real hazard.

Which Black Diamond EA are we talking about?

The name is a problem before you even test the software. “Black Diamond” is shared by several unrelated products, and the marketing blurs on purpose. So the first job is to name the exact one that matches the search demand.

The one people mean is BlackDiamond Special EA, sold at blackdiamondea.info and delivered through Telegram (@bdspecialea) in tiers. It is heavily pirated, so cracked “free download” mirrors are everywhere, which is its own warning sign.

Do not confuse it with three separate products that sound similar. FXAutomater’s Forex Diamond EA is an established commercial robot with a public history. MQL5’s Diamond Black by Fanur Galamov is a $149 night scalper on the official Market. And Black Diamond Trader is a different indicator package again.

Those are distinct vendors with distinct code. Nothing in this review about set files, tiers, or Telegram delivery applies to them. When you read reviews online, check the domain and the seller, because most “Black Diamond EA” pages quietly mix all four.

What does Black Diamond EA claim?

The pitch is built on tiered “accuracy,” which is the first thing that should make you pause. Here is what the sales page states, attributed as claims, not facts.

The vendor advertises up to 95% accuracy on the Unlimited tier, 85 to 95% on Pro, and 70 to 80% on Basic. It also claims a month-to-month return of 80% to 120%.

On drawdown, the sales page claims max DD of 3 to 4% when used for prop or FTMO challenges, and 7 to 12% on live accounts. It describes the system as fixed lot, low risk, works on any pair, on the 30-minute timeframe, with a minimum deposit of $100.

The marketing language leans on “AI-powered” and “verified performance.” Both phrases do a lot of work in the copy and almost nothing in the evidence, which we will get to.

Notice the structure. Paying more supposedly buys a higher win rate: $300 Basic, $700 Pro, roughly $2,500 Unlimited. For a deterministic algorithm, that makes no sense.

The same code either wins 95% of the time or it does not. Accuracy is not a subscription tier you unlock with a bigger payment.

What the numbers actually show

Here is the honest core. There is no credible, independently verified, real-money track record for this EA. No Myfxbook or FXBlue account that is broker-verified, track-record-verified, real-money, and multi-year, substantiating the headline figures. What exists is vendor screenshots, backtests, and unverified self-reported pages.

That matters because screenshots and backtests are the easiest numbers to produce and the least meaningful. A backtest is a curve fitted to the past. A screenshot is a moment. Neither survives contact with a live spread, slippage, and a losing month.

Now the 80 to 120% monthly claim. Do the compounding math and it falls apart. A steady 100% per month turns $1,000 into over $4 million in a year. Nobody trading a $100 minimum deposit is quietly doing that in silence and still selling a $300 EA on Telegram.

Sustained triple-digit monthly returns are not a real edge. They are the signature of leverage stacked on top of an averaging system that works until one trend wipes the account. The number is not impressive. It is a warning label.

One third-party review that dug into the developer’s self-reported Myfxbook found the results unstable, with a poor profit-to-drawdown ratio, scoring it around 2 out of 5. That is the opposite of the “verified performance” the sales page promises.

So treat every performance figure as unverified. Not because we assume bad faith as a fact, but because the burden of proof sits with the seller, and the proof is not there.

The martingale problem

This is the part that decides the review. The EA is marketed as “fixed lot,” which implies one trade, one size, no averaging into losers. That is the safe-sounding story.

The distributed set files tell a different one. They expose an optional martingale toggle plus an auto-lot-increase option. Users report the EA stacking 3 to 9 positions at once and taking large drawdowns on trending markets and small accounts.

Read that again. A system branded low-risk and fixed-lot ships with the exact switches that blow accounts up. Whether the switch is on by default or not, it is in the code you are paying for.

Martingale means you add to a losing position and increase size to “average down,” betting the price snaps back before your margin runs out. It wins often, in small amounts, and then loses everything at once when the market trends against the stack.

Averaging into losers is the classic account-killer because the math is against you. Each added position needs a smaller and smaller reversal to break even, but your total exposure balloons, and one failed reversal takes more than every prior win combined.

Gold makes this worse. If you run a martingale sequence on XAU/USD, gold’s price swings of tens of dollars per ounce mean each averaged position adds real cash exposure fast. A move of 30 to 50 dollars per ounce against a stacked position is common on a normal day, and on a small account that sequence balloons before any reversal saves it.

If you take one thing from this review: an optional martingale inside a “low risk” EA is the story. Everything about position sizing and survival lives here. Read our forex risk management for beginners guide before you let any robot size trades for you.

Red flags checklist

Line the signals up and the pattern is hard to miss. Any one of these is a caution. Together they are a wall.

• Anonymous vendor. No identifiable company, sold through a Telegram handle. If it goes wrong, there is nobody to hold accountable.
• No refund. The sales page states no money-back guarantee. You pay $300 to $2,500 up front with no recourse.
• No verified track record. Screenshots and backtests only, no broker-verified real-money Myfxbook.
• Tiered “accuracy” pricing. Paying more supposedly buys a higher win rate on the same algorithm, which is nonsensical.
• Martingale and auto-lot in the set files despite fixed-lot, low-risk branding.
• Heavy piracy. Cracked copies everywhere, so even the “buy” version has no integrity guarantee.
• Vague strategy, no clear hard stop. The marketing avoids naming a defined per-trade stop-loss.

We are not calling it a scam as a flat fact, because we cannot prove intent. We are saying the verifiable parts are troubling and the impressive parts are unverified. That gap is the whole review.

Can you use it to pass a prop firm challenge?

The vendor markets the low 3 to 4% drawdown figure specifically at prop and FTMO challenges. This is where the mismatch between story and mechanics gets expensive. If you are new to this, start with what a prop firm is.

Prop challenges live and die on drawdown rules. Most enforce a hard daily loss limit and a hard maximum loss, and breaching either ends the challenge and your fee. Those rules are designed to fail exactly the kind of account a martingale produces.

A martingale posts a smooth equity curve right up until it does not. The one day the averaging stack fails, the drawdown is not 3 to 4%. It is the drop that trips the daily limit in a single sequence and burns the evaluation fee.

So the pairing is backwards. The strategy that produces the pretty low-drawdown screenshots is the same strategy most likely to breach a hard drawdown rule on a bad day. A challenge is the worst place to find out your EA averages down.

How to evaluate any EA before you buy

Do not take our word on this one product. Learn the checks, and you can vet every EA that lands in your inbox. Here is the sequence I run before spending a cent.

Demand a real Myfxbook Track-Record-Verified account. Not a screenshot, not a backtest. A live account with both the broker connection and the track record verified, ideally multi-year, on real money. No verified account, no sale.

Forward-test on demo yourself. Run it on a demo for weeks across ranging and trending conditions. A backtest shows a fitted past. A forward test shows how the code behaves on data it has never seen.

Open the set file and search for martingale, grid, or lot-increase. If the parameters include martingale multipliers, averaging distance, or an auto-lot toggle, you now know the real risk profile regardless of the marketing.

Insist on a hard stop-loss per trade. Every position needs a defined worst case in the code. If the strategy has no fixed stop, its worst case is your whole account.

Require a refund window. A seller confident in the product offers one. An anonymous seller with no refund is telling you something.

A safer path than a black box

The pull of an EA is understandable. You want the market handled while you sleep, especially on a small account where every loss stings. That wish is exactly what a $2,500 “95% accuracy” pitch is built to sell.

The trouble with any black box is that you cannot fix what you cannot see. When it draws down, you do not know why, so you cannot tell a normal losing streak from the start of a blow-up. You are a passenger.

Learning even a simple, transparent method changes that. You can watch a small, honest system work and understand every trade it takes. We walked through one in an honest look at a simple RSI EA, warts and all, so you can see what realistic looks like next to “95%.”

If you want the checklists and the plain-English breakdowns as we publish them, our email list is where they go first. No hard sell, no guru promises. The goal is that you can evaluate the next Black Diamond yourself and walk away before the money leaves your hands.

Frequently asked questions

Is Black Diamond EA a scam?

We cannot prove intent, so we will not call it a scam as a flat fact. What is verifiable: it exists, is sold in tiers, is heavily pirated, its set files contain martingale and auto-lot options, and users report position stacking. What is not verified: every performance headline, including the 95% accuracy and 80 to 120% monthly return the vendor claims. Judge it on that gap.

Is there a free download of Black Diamond EA?

Cracked “free” copies circulate widely, which is one of the clearer signs of a low-trust product. Running a pirated EA is a security risk on the account you attach it to, and a cracked file can be altered. There is no safe free version, and the piracy itself tells you how the market treats the software.

What returns does the vendor claim?

The sales page claims up to 95% accuracy on the Unlimited tier, 85 to 95% on Pro, 70 to 80% on Basic, and a monthly return of 80% to 120%. All of these are unverified vendor claims. No broker-verified, real-money Myfxbook account substantiates them, and steady triple-digit monthly returns are not consistent with how real trading edges behave.

Does Black Diamond EA use martingale?

It is branded as fixed lot, but the distributed set files expose an optional martingale toggle and an auto-lot-increase option. Users report it opening 3 to 9 positions at once. So it can run as a martingale or grid that averages into losers, which is the central risk and contradicts the low-risk marketing.

Can I use it on gold?

The vendor says it works on any pair, but gold makes any averaging strategy more dangerous. XAU/USD swings tens of dollars per ounce in a normal session, so a stacked, size-increasing sequence adds cash exposure fast. On a small account, a 30 to 50 dollar per ounce move against a martingale stack can balloon the drawdown before any reversal helps.

How much does Black Diamond EA cost?

The vendor prices it in three tiers: Basic at $300, Pro at $700, and Unlimited at roughly $2,500, sold via Telegram with PayPal, Visa, or Bitcoin. There is no stated money-back guarantee and no identifiable company behind it. The tiered pricing supposedly buys higher accuracy, which does not make sense for one fixed algorithm.
