How to Invest in Forex With a Robot on Your Own Account

Your own account

Most ways of putting money into a trading strategy involve handing it to someone. A fund, a managed account, a PAMM: the manager trades, you get a statement.

Running an expert advisor is a different shape entirely. The account is opened in your name at a broker you choose, you transfer money into it yourself, and the software runs on a MetaTrader 4 terminal you control. What you buy is a licence to use a program, not a service that looks after money.

That is also the honest version of the trade-off. There is no manager to blame and no manager to stop you: the decisions are yours, including the decision to leave it running through a bad month.

What you set up

• A broker account in your name, with MetaTrader 4 and a leverage the strategy can work with.
• A VPS, so the terminal stays online. In the EURUSD Patient simulation (2010–2025, Dukascopy data) the strategy held open exposure through almost the whole period, so an offline terminal is not a neutral state.
• The expert advisor and its set files: you choose one to four pairs — EURUSD, GBPUSD, EURCAD and AUDCAD — then Patient, Active or both for each, and each chart loads its own preset at your licence level. Patient adds to a basket less often and holds a smaller worst case; Active adds more often, returned more in the backtest and reached a larger worst case.
• The capital that level was sized against, which is the part people skip.

None of that requires learning to trade. It does require being willing to read a drawdown figure and decide whether you can live with it.

The number that decides

A grid without a stop loss carries its losses as open positions. The relevant question is not the average return; it is how far under water the account goes at the worst moment, because that is what you have to sit through without closing everything in a panic.

In the simulations (2010 to September 2026, Dukascopy data, euros at fixed rates), K3 at Horizon level had a worst floating loss of €3,704 on 22 October 2012 — and our reference figure is €22,500 for it; K1 at Horizon floated −€4,701 on 14 February 2011 — and our reference figure is €28,800, in both cases the reference figures of their records added up. Summit multiplies both sides by five and Zenith by ten.

How Kestrel applies this

Kestrel EA is a grid expert advisor for MetaTrader 4: it opens from its own signal, adds to the basket in small, capped steps when price moves against it, and closes the whole basket together at its target. It never closes a single trade at a loss; until the basket closes, the loss is floating.

Like the kestrel that hangs still in the wind, it waits, holds and closes once — but the decision to keep it running through a month like April 2015, which closed −€1,301 on the €10,000 reference account before May closed +€1,629 (simulated, 2010–2025), is a decision a person has to make.
