Common jobs, in MQL5 and in Forge

Forge API 1Updated 14 Oct 2026

One card a job. Each answer is one line, not a whole file.

Act once per new bar

In MQL5

text

if (iTime(_Symbol, _Period, 0) != last_bar_time) { ... }

In Forge

python

Nothing to write: compute() and on_bar see each closed bar once.

One trade per bar

In MQL5

text

Remember the bar of the last trade and skip until the next.

In Forge

python

One new trade per bar on each symbol is the default. fg.Filter.max_trades(per="day", n=1) caps a day.

fg.Filter

Manage only your own trades

In MQL5

text

Filter positions by magic number.

In Forge

python

tag="breakout" on the entry, then ctx.close(tag="breakout").

fg.Signals

Skip entries when the spread is wide

In MQL5

text

if (SymbolInfoInteger(_Symbol, SYMBOL_SPREAD) > max) return;

In Forge

python

filters=[fg.Filter.max_spread(pips=2)]

fg.Filter

Trade only in set hours

In MQL5

text

Compare TimeCurrent() hours with start and end inputs.

In Forge

python

filters=[fg.Filter.session("08:00-17:00", tz="Europe/London")]

Write the zone the hours are in. Broker server time has no zone name.

fg.Filter

Close everything at a total profit or loss

In MQL5

text

Sum the profit of open positions and close them all past a level.

In Forge

python

basket = fg.Exit.basket(profit_cash=200, loss_cash=100)

fg.Exit

A grid with a cap

In MQL5

text

Place pending orders at fixed steps up to a maximum count.

In Forge

python

In on_fill, place the next level with ctx.order(fg.Order.limit(...)) while len(ctx.positions()) is below your cap.

Forge has no grid declaration in FORGE_API 1, so the grid is written in a hook.

fg.Order

Round lots to the broker's step

In MQL5

text

NormalizeDouble(lots / step, 0) * step, then clamp to the minimum and maximum.

In Forge

python

size=fg.Size.risk_pct(1.0) in fg.Signals. Forge rounds down to the lot step and refuses a size below the minimum.

fg.Size
