Cuprum

It performed better on the data it had never seen.

That is the first thing worth knowing about Cuprum, because it is the

first thing a serious buyer doubts. Its components were tuned on one

window of copper history and then tested on two they were held out of.

In the strategy tester, profit factor on the tuning window was 1.23. On

the out-of-sample window that followed it, 1.69.

Most systems post their best number on the period they were fitted to.

This one did not, and the chart in the screenshots shows exactly where

each window begins and ends so you can check the claim rather than take

it.

Over the full test — 1 February 2024 to 4 November 2026, every tick,

9,809 trades, a 25-point spread modelled throughout — a $10,000 account

ended at $69,222. Profit factor 1.35. The deepest the closed-trade

balance ever fell from a high was 13.9 per cent. Twenty-eight of the

thirty-four months finished in profit.

Why five strategies instead of one

A single strategy has exactly one way of being wrong, and nothing else

running when the market stops suiting it.

Cuprum runs five independent strategies side by side on one copper

chart. Each has its own signal, its own stop and target, its own magic

number and its own share of account risk — reward-to-risk ratios from

1.0 to 2.5, one of them long-only, all five visible and adjustable in

the inputs. Five versions of one idea diversify nothing, so these were

chosen to be unalike.

Tens of thousands of candidate configurations were tested and rejected

before these five were kept, every test carrying a modelled spread,

because a strategy that only survives at zero cost is not a strategy.

They were then validated together, at the sizing they actually trade —

five strategies that each look good alone can still be the same bet

five times.

What stands between a signal and an order

Position size is calculated from your account balance and the distance

to the stop, so it falls as the account falls and recovers as it does.

Two checks can stop an order outright, and two more shape it before it

is sent:

- Margin level floor — the EA asks your broker what the margin level

would be once the order filled, and refuses the order if it would fall

below this. Checked against the broker's own figure, not estimated.

Default 200%.

- Too small to trade — if the smallest position your broker allows

would risk more than this share of equity, it stands down and takes no

trade at all, rather than trading over its own risk budget. Default

1.5%.

- Risk per strategy — each order is sized so being stopped out costs

this share of balance, then rounded down to your broker's lot step.

Default 1.0% each.

- Stop floor — the stop is held at least this multiple of the spread

away from price, so it is never placed inside the noise it has to

survive. Default 8x.

Every position carries a stop loss and a take profit from the moment it

opens. There is no martingale, no grid, no averaging into a loss and no

recovery mode. A losing trade is closed at its stop.

What it needs

Copper cash CFD, quoted in US cents per pound — brokers spell it COPPER,

XCUUSD or COPPER.P. This is not for a copper futures contract; the

contract size differs and position sizing would be wrong by a large

multiple. M30. A hedging account, because five components hold positions

at once. $500 minimum, $2,500 recommended — below $500 the lot step

rather than your risk setting starts choosing the position size, and the

screenshots show exactly where that line falls.

Check it yourself

Download the demo and run it in the strategy tester on your own broker's

copper feed, over your own dates, at your own deposit. Copper

specifications vary between brokers more than most instruments, and the

only test that tells you what this does on your account is one run

against your account's own conditions.

Past testing describes the past. No backtest, of any length or quality,

is evidence of future results.
