Trading bots & indicators

Custom trading bot development — built from your rules

You bring the strategy, I write the code: indicators, strategies and bots for ATAS, NinjaTrader 8 and TradingView. Source code included, no signals, no profit promises.

How I work

What you get

Spec

Rules in writing before I build

Entry, exit, stop, target, edge cases. Anything ambiguous gets settled first, so nobody builds the wrong thing.

Source code

The code is yours

You get the source code and the ready-to-load file for your platform, plus a short guide to every setting.

Testing

Checked before delivery

I test the logic in replay or the strategy tester against your rules. That proves the code does what you asked. It does not prove the strategy makes money.

Past work

Recent projects

Clients from the US, France and elsewhere, most of them via Fiverr. I do not name clients; the projects are described as they were built.

A trader’s own absorption logic as an ATAS bot

The client had his entry logic as an indicator. It became an ATAS bot with native absorption detection, a setup panel, stop, target, break-even and two partial targets. A follow-up order for a second strategy variant came next.

Anchored volume profile with a developing POC

Volume profile over a freely anchored range, with a developing point of control, value area (VAH/VAL), alerts and hotkeys.

“The indicator that I requested came out to work exceptionally well.”

Fixed-time breakout with OCO orders

At the set time the strategy reads the close of the last candle and places a buy stop above and a sell stop below. One side fills, the other is cancelled, stop and target in ticks, one trade per session. A licence lock was added as a follow-up order.

Stop-and-reverse strategy, dashboard and oscillators

Across several orders: a stop-and-reverse strategy with resting orders and hard safety rules against multiple reversals within one candle, a dashboard strategy, and an indicator that combines Williams %R and comparative strength with a combined signal and alerts.

VWAP strategy with webhook signals for a bot service

Reworked an existing Pine strategy so it sends its entries and exits as JSON webhooks to WunderTrading, which places the orders at the exchange.

Process

From your rules to a working bot

  1. 01

    Send your rules

    Platform, market, timeframe and your rules. Screenshots, notes or existing code help.

  2. 02

    Spec and fixed price

    I write the rules down unambiguously and ask where they are open. Then the price is fixed.

  3. 03

    Build and test

    Code to spec, tested in replay or the strategy tester. For strategies I check orders, stops and edge cases.

  4. 04

    Delivery and changes

    Source code, ready file, guide. Deviations from the spec are fixed; new ideas get their own quote.

If the bot will run on a prop firm account, I check whether that firm allows automation before I build.

Pricing

Fixed price after the spec

Past orders

from $110

Pine strategy with webhook signals from $110. ATAS indicators and strategies so far $265 to $350. The exact price is fixed after the spec, before I start.

FAQ

Frequently asked questions

Do you sell ready-made bots or signals?

No. I only build your own strategy from your rules. I do not sell systems, signals or strategy recommendations.

Will my bot be profitable?

Nobody can promise that, and neither can I. I make sure the code implements your rules exactly. Whether the rules make money is up to the market.

Do I own the source code?

Yes. You get the complete source code and can change it or have someone else extend it.

Can I run a bot on a prop firm account?

It depends on the firm and changes often. Apex prohibits automation, new Topstep accounts run only on TopstepX, Lucid allows bots with conditions. Details in the guide to prop firm rules.

Can you convert a TradingView indicator to ATAS or NinjaTrader?

Yes. That makes sense when you need order flow data or want orders to come straight from the platform. Not every Pine function has a direct counterpart; I check that first.

How long does a project take?

A clearly described indicator is usually done within a few days. Strategies with order management take longer. You get the date together with the fixed price.

Notice: I write software to your specification. This is not investment advice and not a signal service. You alone decide on strategy, sizing and risk. Trading futures, CFDs, forex and crypto is risky and can lead to the loss of your entire capital. Backtests and past results say nothing about future results.

Inquiry

Send me your rules. You get a written spec and a fixed price.

The more precise the rules, the more precise the quote. Open questions get settled before I build, not after.
