Create a custom MT4 or MT5 indicator from plain words

What you can build

• Signal arrows on the chart when your conditions are met, with pop-up, sound, email or push alerts.
• Lines, histograms and coloured bands from moving averages, RSI, MACD, ATR, Bollinger Bands, Stochastic, price action and session times.
• Multi-timeframe indicators that read a higher timeframe and draw on the current chart.
• Signals on closed bars, so arrows do not repaint, or on the live bar when you want them early: you choose.

Correct buffers, the first time

Indicator code fails in quiet ways: the wrong number of buffers, arrows drawn on the wrong bar, values that change after the bar closes, or a program that recalculates the whole history on every tick and slows MetaTrader down. The Lab sets buffers, plots and calculation limits correctly for MT4 and MT5, and its checks look for these mistakes before you see the code.

From indicator to EA, when you are ready

When you like what the indicator shows, the Lab can turn its signals into an Expert Advisor that trades them, with the risk settings you choose. Every change is a new version, so the indicator itself is kept as it was.

Questions

Can AI write an MT4 or MT5 indicator?

Yes. Describe what the indicator should calculate and draw; the Lab writes it in MQL4 or MQL5, compiles it with MetaEditor and checks it, then shows you the result before you download.

Will my indicator repaint?

Not when you ask for signals on closed bars: an arrow that appears then stays where it is. Say so in your description, and the checks look for it.

Can I change an indicator I already have?

Yes. Upload the .mq4 or .mq5 file and describe the change in plain words, such as adding an alert or a second line. The Lab makes it as a new version.
