Tradetron: Builder, Marketplace and the Broker in Between

Builder or marketplace: two different risks

As we understand it, Tradetron does two jobs that are worth keeping apart in your head. It is a place to build a strategy without writing code, and it lets strategies be shared with other users. The first job turns your rules into orders. The second puts other people's rules in front of you.

A builder is a tool, and its risk is your own mistakes: a rule that says something other than you meant, a size that is too big, a case you did not think of. A marketplace is a shop, and it adds a different risk, which is that you may not fully understand or fully see what you are following. For the basics of the first, see algorithmic trading. For what following someone else involves, see copy trading, because a follower's result can differ from the leader's.

The broker sits in the middle

A strategy on a platform like this does not trade by itself. It sends orders through a broker, and the broker's own rules, margin requirements and outages still apply. A strategy can send an order that a broker rejects, or one that is filled later than the strategy expected, and the platform cannot make either of those go away.

If the broker offers margin or leveraged products, a strategy can lose faster than its author's record suggests, because leverage turns a modest move into a large share of the account. See margin call for what happens when the account can no longer carry the position. The example that follows is that effect, in numbers.

Worked example: one strategy, four account sizes

All numbers are made up, and the margin rule is simplified. It is not a Tradetron strategy and not any broker's rule. A shared strategy holds one contract with a value of $25,000. The broker sets aside 10% of that as margin, which is $2,500. The author's record, on a $30,000 account, shows a worst open loss of $1,500. Four people consider following it with accounts of different sizes.

Calculated by us on 3 Nov 2026, exact. On the largest account the record the author showed is mild: the worst moment cost 5%. On the smallest account the same contract ties up 83% of the money before it moves at all, and the same worst moment is bigger than what is left. The strategy has not changed. The account has.

Treat this as the question to ask of any shared strategy: what account size was the record made on, and what position size does the strategy hold relative to it? A record quoted in percent on a big account does not transfer to a small one.

Paper first, then small

1. Run any strategy you are considering in a paper mode first, for long enough to cover a quiet stretch and a sharp one.
2. Check whether the paper fills use real market data and realistic costs, or cleaner ones.
3. Compare the paper fills with the prices your own broker would have given on the same days.
4. Only then consider a very small live amount, sized so the loss in the table above would not matter to you.

Our pages on paper trading and forward testing cover what a simulated run can and cannot show.

Reading a shared strategy's page

• Can you see the rules? If not, you are following a stranger's decisions.
• What are the position sizes? Against which account size was the record made?
• What is the maximum open loss? In dollars and as a share of that account.
• How long is the record? Does it include a sharp, losing stretch?
• Is the record live or rebuilt from the past? And does it include the costs a follower would pay?

The limits of this page

Nothing here judges whether Tradetron works or how safe it is, and no other product is set beside it. The contract, the margin and the accounts are invented. Crypto-assets and leveraged products can lose all the money put into them, and past or simulated results are not a guide to future results.
