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.
TradingView · Pine Script
Indicators, strategies and alerts for TradingView, built from your rules and without repainting. If the signals should trade automatically, they go to a bot service by webhook.
Services
Plots, zones, labels, tables and higher-timeframe data, cleanly without repainting.
Entry, stop, target and position size as a Pine strategy, so you can check your rules in the Strategy Tester.
Alerts with a clear message or JSON payload that a bot service such as WunderTrading turns into orders.
If you need order flow or want orders to come straight from the platform, I move the logic over.

Higher-timeframe data and signals on the open candle can change after the fact. I build so that a signal stays once it appears.
“Once per bar” and “once per bar close” behave very differently live. For bots it is almost always: at bar close.
The tester fills orders on bar data. Results there show whether the rules are implemented correctly, not what they will do live.
Webhook alerts need a paid TradingView plan and two-factor sign-in. The bot service defines the message format.

A Pine strategy with webhook signals came to $110. Larger indicators with many options cost more. The price is fixed before I start.

Only to a limited extent. The usual setup: Pine creates the alert, a webhook sends it to a bot service or broker bridge, which places the order. Alternatively I move the logic to ATAS or NinjaTrader.
A signal that appears once does not disappear and does not move to another candle later. That is the precondition for alerts and backtests to match.
Yes, the complete Pine code. You can keep it private, publish it as a protected script or publish it openly.
Yes. Send the code and describe what it should do and what it does instead. You get an assessment and a fixed price.
If the service accepts webhooks from TradingView, yes. So far I have built this for WunderTrading. For other services I build the message from their documentation.
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.

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