Custom Indicator Development — TradingView (Pine Script)
Custom indicator and strategy development on TradingView, written in Pine Script — for traders and firms whose edge isn't in the built-in indicator library.
TradingView's built-in indicator library covers the common cases well — moving averages, RSI, MACD — and stops being useful the moment a trader's actual edge is something more specific than the default toolkit. A strategy based on a genuinely custom combination of price action, volume, and market structure has nowhere to go except a script written from scratch, and most traders either can't write Pine Script themselves or don't have the time to.
The alternative — downloading and lightly modifying a public script — usually doesn't hold up. Public scripts are built for a general audience, not your specific logic, and small tweaks to code you don't fully understand are how strategies quietly break in ways that only show up once real capital is on the line.
Backtesting and alert configuration are where a lot of DIY and freelance work falls apart, too — a script that plots correctly on the chart but has alert conditions or backtest assumptions subtly wrong produces confident-looking results that don't reflect how the strategy would actually perform live.
Algotrax writes Pine Script from your actual logic, tests it rigorously, and documents it so you understand exactly what it does — not a black box you're trusting blind.
What's included
Custom indicators built from your own logic, not a modified public script
Strategy scripts with backtesting and alert conditions configured correctly
Multi-timeframe and multi-symbol logic where a single-chart indicator falls short
Pine Script v5/v6 migration for older scripts that need modernising
Documentation so you understand exactly what the script does, not a black box
How it actually runs
Logic specification
Your trading logic captured precisely — the exact rules, thresholds, and conditions — before any code gets written, so the script matches your actual strategy, not an approximation of it.
Script development
Written in Pine Script v5/v6, structured cleanly enough that it can be maintained and modified later, not a tangle of unexplained conditions.
Backtest configuration
Set up to reflect realistic execution — commissions, slippage assumptions — not an idealised backtest that flatters the strategy.
Alert setup
Configured correctly so alerts actually fire on the conditions you specified, tested against historical data before you rely on them live.
Documentation & handoff
A clear explanation of what the script does and why, so you're not dependent on remembering, or re-explaining, the logic months later.

What most agencies get wrong here
Modifying a public script without understanding its underlying logic.
Small changes to code you don't fully understand are how strategies break in ways that only surface with real capital on the line.
Backtesting with unrealistic assumptions.
A backtest with no commission or slippage modelling flatters every strategy equally, which means it tells you nothing useful about any of them.
Skipping alert-condition testing.
A script that plots correctly but never actually fires the alert you need it to is worse than no script at all.
Treating a script as a black box.
Not understanding what your own indicator does is a real risk the moment market conditions shift outside whatever it was tested against.
How the engagement works
Priced per script based on logic complexity — a straightforward indicator is a much smaller engagement than a multi-condition strategy script with backtesting and alert logic.
A specification conversation happens first, free of charge, to confirm the logic is precisely understood and the scope is accurate before any commitment.
Revisions to refine the logic against backtest results are typically included up to an agreed point; further strategy iteration beyond the original spec is scoped as separate follow-on work.
Once the script is delivered and documented, it's yours to actually understand — you know exactly what it does and why, not just that it works, so market conditions changing doesn't leave you trusting a black box.
Getting started is a short, free specification conversation — the logic gets confirmed precisely before any commitment or cost.
