Prop Firm Robots App What South East EA Is
South East EA by Sugianto (MQL5 market, $250) is a multi-symbol grid the vendor himself describes as "grid averaging with mild martingale": when a trade moves against the position, more are added at better prices, lot size rises moderately, and the whole basket closes in profit. On top come a virtual stop-loss/take-profit, a news filter and a drawdown cut-loss that flattens everything at a set threshold. The EA was released in August 2021, is maintained (version 4.50 from June 2026) and ships set files for 20 pairs.
What the Design Means
A grid with a martingale component earns because the market comes back, not because the EA predicts direction. As long as it comes back, baskets close in profit and the balance curve looks calm. In between, though, the open baskets can sit deep underwater; anyone forced to close at that moment realises the full loss. The balance shows none of this — you only see it in equity and floating loss.
In practice "mild martingale" means: each add-on is larger than the last, and a long adverse run multiplies the position size. And because the EA trades many pairs in parallel and often holds baskets for several days, it keeps baskets open practically every weekend. A Monday gap in the wrong direction then hits not one pair but every correlated one at once — our guide to correlation and combined drawdown explains why that is concentration risk, not a portfolio.
What speaks for the vendor: he hides none of this. The product page explicitly calls $500 "high risk", advises $2,000, documents the martingale component and ships the drawdown cut-loss with it. That is more openness than many pricier competitors offer.
If you want to check South East yourself, start on a demo account and watch not the balance but equity, floating loss, the lot sizes in the trade log and how many baskets stay open over the weekend.
Cost & Usability
$250 to buy or $150 per month to rent is cheap next to the $800–3,000 charged for comparable grid systems. Setup is set-file work: one chart per pair, load the set file, set the cut-loss threshold. Set the drawdown cut-loss deliberately tight and limit the number of pairs traded simultaneously — the EA supports both. An ECN broker with a hedging account is mandatory (see the EA broker comparison).
Who the Design Suits (and Who It Doesn't)
Suits experienced grid traders with capital well above the minimum deposit who actively set the cut-loss, consciously carry weekend exposure and budget the EA with a hard cap inside an EA portfolio.
Does not suit prop-firm accounts with hard drawdown rules, accounts below the deposit the vendor names, copy-trading subscribers who only see the balance curve — or anyone who believes a grid's returns are repeatable.
Assessment
South East EA is an openly described, maintained and inexpensive grid system with a martingale component. Its returns depend on the market coming back; the risk sits in the open baskets, not in the balance. Anyone running it needs a deliberately set cut-loss, a capital buffer and an eye on equity.
South East EA is not available from our partner AlgoTradingSpace (ATS). We still grade it with the same formula as every other EA, but we do not link to the vendor.
