Ports
TradingView → MetaTrader
You found an indicator on TradingView that does what you want. It does not exist
for MT4 or MT5, and the author has no plans to make it. Send the Pine script or
the link, and get a native build for both platforms — same logic, same signals,
running on your broker's data instead of somebody else's feed.
Most of the toolkit on this site started as exactly this job, so
the Products page doubles as the portfolio. Where a Pine feature has no
MetaTrader equivalent — higher-timeframe alignment, repainting, Pine's drawing
model — you are told before the work starts, not after.

Market submission
Getting an EA past MQL5 Market review
Rejected again, and the moderator's note does not explain it in terms you can
act on. The causes are usually the same short list: margin and volume never
checked before an order, stops level and freeze level ignored, order limits
unhandled, or a crash the tester finds on a symbol you never tried.
Send what you have and get it back in a state that passes, with a
note on what was wrong so the next one you write does not repeat it. The strategy
is not touched — only what stands between it and approval.

Prop firms
Compliance layer for challenge accounts
The EA works. The challenge rules will still fail it: a daily loss cap it does
not know about, a total drawdown ceiling it cannot see, news windows it trades
straight through.
A compliance layer bolts those limits on from outside. What it enforces:
- Daily loss ceiling, measured from the firm's own daily reset time
rather than your terminal's midnight — the two rarely match, and that mismatch
is how accounts fail on a technicality.
- Total drawdown ceiling, tracked against the high-water mark or the
starting balance, whichever your firm uses.
- Trading hours and news blackouts, so an EA does not walk into a
release the rules forbid trading through.
- Position sizing tied to the remaining allowance, so the last trade
before a limit cannot be the one that breaches it.
- A hard stop that closes everything and stands down for the day once a
threshold is near, rather than hoping the next tick is kind.
The strategy underneath is left alone, so what passes the
challenge is still the thing you tested. Tell me which firm and which programme
— FTMO, MyForexFunds, The5ers and the rest all count their limits slightly
differently, and the difference is the whole job. What this cannot do is rescue
an EA that loses money: it enforces limits, it does not create an edge.
Custom builds
Test the idea, then build it
Two jobs, priced apart on purpose.
Testing an idea is the cheap one. Describe the strategy in plain words —
entries, exits, which market, which timeframe — and get a backtest that says
whether it is worth building at all. You get the equity curve, drawdown, profit
factor and trade count across several market regimes, plus a straight answer on
whether the result survives a change of parameters or only works at one exact
setting.
Building it is the larger job, and it starts from that answer rather than
from hope. Indicator, expert advisor or utility; MQL4 and MQL5 both, including
converting between them. You get the source, not just a compiled file.
Plenty of ideas do not survive the testing step, and finding that
out for a small fee beats finding it out after paying for a build. If the test
says no, the honest answer is no — and you have lost the price of the test rather
than the price of an EA.
Reviews
Commissioned reviews
Send a tool and get a backtest across several market regimes, the settings file,
and a written verdict — published here with your product named, or kept private.
A paid review can still conclude the tool is bad, and it will say so. That is
what makes the ones that pass worth reading.
