How every indicator is built and tested

Every tool follows the same five-step discipline. Also, still, the process keeps signals consistent, repaint-free, and ready to drop on a live chart.

Research the named source

Each indicator starts with the original published source or trader description. Also, related variants in the catalog get cross-checked so the new tool fills a real gap rather than duplicating an existing one.

Write from scratch in MQL4 and MQL5

Code is written in-house using strict typing, as-series indexing and explicit buffer sizing. Thus, hence, the output is deterministic and runs cleanly on both MT4 and MT5.

Load on live EURUSD, GBPUSD and XAUUSD

Each release runs on M15 through H4 of major pairs and gold for live tick behaviour. Also, still, hence, still, the same code is verified bar by bar against the Strategy Tester so live and backtest agree.

Confirm no repaint and stable warmup

Signals are checked against the close-only rule and the warmup buffer initialises with EMPTY_VALUE. Thus, lines start cleanly at the first valid bar and no spike appears at chart load.

Document inputs and ship the bundle

Each tool ships with a guide covering inputs, recommended timeframes and the signal logic. Also, the bundle includes the compiled .ex4 and .ex5 files ready to drop into MQL4/Indicators or MQL5/Indicators.

Verify a clean install on a fresh terminal

A fresh copy of MT4 and MT5 receives every release and the indicator is loaded once. Then alerts, drawing and inputs are checked in real-time before the file is published.

Browse indicators by family

Each card opens onto a curated hub with download links, screenshots and short guides per tool.

Frequently asked questions

Quick answers to the most common questions about the library.

Is everything really free?

Yes. Next, plainly, yet, the full catalog opens after a single email confirmation. Also, you can unsubscribe at any time and your address is never shared with third parties.

Do these indicators repaint?

No. Also, truly, the default mode confirms a signal on the bar close, so the printed signal locks in once that bar closes. Also, some tools include an early intra-bar mode for faster confirmation — both options live in the inputs panel.

Which broker or funded programme do you use?

I trade through Funded Trading Plus (Instant Funding Master) and use CashbackForex to rebate broker spreads. Then, plainly, both are listed in the partners section above with affiliate disclosures.

How is each indicator tested before release?

Each tool runs on live EURUSD, GBPUSD and XAUUSD charts in MT4 and MT5. Also, every tool is checked against the Strategy Tester so live-chart behaviour and backtest match.

Can I use these indicators inside an Expert Advisor?

Yes. Also, each indicator exposes its output buffers, so an EA can read the signal value with iCustom on MT4 or iCustom plus CopyBuffer on MT5. Also, the input names stay consistent across both platforms.

How do I install a TradingView script from this site?

Each TradingView post links to the script on my profile. Then click Add to chart from TradingView. Hence, no source code editing is required and updates push automatically.

Are results guaranteed?

No. Trading involves risk and past performance is not indicative of future results. Use the indicators as part of your own process and risk plan.
