How to Combine Two Indicators in Tradingview Pine Script with Chatgpt 2026 Easily

Before asking for a merge, get ChatGPT to write out each indicator as its own clean, working script: one labeled "RSI Indicator Only," the other "MACD Indicator Only." Each one starts with a version header and an indicator() declaration, followed by clearly separated Inputs, Calculation, Plots, and Alerts sections. Keeping them separate at this stage matters because it's easier to spot a mistake in a 20-line single-indicator script than in a 60-line combined one, and the same input names get reused when asking for the merge in the next step.

Left to its own defaults, ChatGPT tends to write //@version=5 at the top of the script, which is what it produced for both the RSI and MACD examples here. That still compiles and runs on TradingView; the version pragma pins the script to that language's rules.

But TradingView's current language version is Pine Script v6, and a v5 habit carried into hand edits later can cause confusion, most visibly through the transp= parameter inside plot() calls (used in the MACD example below), which v6 removed in favor of color.new(color, transparency). Asking ChatGPT directly, "write this in Pine Script v6," avoids the mismatch from the start. If existing v5 scripts are being kept, that's fine too, just don't mix a v5 script's transp= styling into a v6 merge without converting it first.

Paste the first script into TradingView's Pine Editor and click Add to chart (or Update on chart, if a version of it is already on the chart) to confirm it compiles and plots correctly before adding any complexity. In the example run, the MACD-only script adds its line, signal line, and histogram in a separate panel below a live BTCUSD five-minute chart, with the indicator name and settings shown in the panel header. If a single indicator throws an error at this stage, fix it here; debugging one script is simpler than debugging two that have already been merged.

With both scripts verified individually, paste them into the same ChatGPT conversation and ask it to combine them into a single indicator, keeping their "Script 1" / "Script 2" labels intact so it can tell which inputs belong to which indicator. Tell it explicitly to rename any clashing variables (both scripts likely used similar names for length or smoothing inputs) and to keep the indicator title descriptive, something like "RSI & MACD Combo." A good merge keeps the same Inputs / Calculation / Plots / Alerts structure as the originals, with both indicators' logic under one indicator() declaration instead of two.

RSI and MACD are both oscillators that don't belong on the price chart itself, so tell ChatGPT to set overlay=false and keep the combined output in its own panel below price; that's the correct default for this pairing. Combining something like a moving average with price action instead would call for overlay=true, so it draws directly on the candles. Specifying this up front avoids a second round-trip to fix the display after the code is already pasted and tested.

Copy the final combined code from ChatGPT, paste it into a fresh Pine Editor tab, and click Add to chart. In the finished example, the combined "RSI & MACD Combo" indicator renders the RSI line and the MACD line, signal, and histogram together in a single lower panel under the same BTCUSD chart: one script, one panel, both signals visible instead of stacked across two separate indicators.

If the merged script throws an error on paste, copy the exact error message TradingView shows and paste it back into the ChatGPT conversation with the script, rather than hand-debugging unfamiliar Pine Script syntax. Most merge errors come from duplicate variable names ChatGPT missed, a version mismatch between the two original scripts, or a leftover transp= argument from a v5 script that a v6 merge won't accept. Naming the specific error gets a working fix faster than describing the symptom.

Both original scripts already had their own alertcondition() calls: RSI crossing overbought or oversold, MACD crossing its signal line. Once merged, ask ChatGPT to add a new alertcondition that fires only when both are true at once, using an if-then check like a MACD bullish crossover happening while RSI is below its oversold line.

That combined condition is usually the whole reason to merge two indicators in the first place. After adding it, click Update on chart before opening Create Alert; the alert dialog reads conditions from whatever version of the script is currently on the chart, not from the editor tab.
