Pine Script v6 is TradingView's scripting language for building custom indicators and trading strategies. I've been writing Pine Script for about two years, and this cheat sheet collects the operators, data types, and built-in functions I reference most. Whether I'm coding an RSI divergence scanner for AAPL or a trailing stop for ES futures, these are the fundamentals.

If you're wondering what language is Pine Script, it's TradingView's domain-specific scripting language for financial analysis and automated strategies.

Pivot indicators are price-action tools that mark likely support and resistance levels based on historical highs and lows. Finding the right one on TradingView can sharpen your trading approach. These tools hand you clear zones for entry, exit, and stop-loss placement, helping you spot reversals before they happen.

No single Python backtesting library works for every trader. I've tested VectorBT, Backtrader, and a handful of others on real portfolios, and each one has sharp edges you only find after you commit. If you're coming from TradingView, the concepts on Pine Script optimization practices transfer directly to Python strategy logic. A Python backtesting library is a software toolkit that lets you simulate a trading strategy against historical price data before risking real money. If you need that verdict up front: VectorBT wins on speed, Backtrader wins on realism, and Backtesting.py wins on simplicity. Pick the one that matches where your bottleneck is.

The QQE indicator is a momentum oscillator that smooths out RSI's rough edges to give you cleaner signals. I started testing it on SPY after getting burned by a false RSI reading in March 2025, and it surprised me how much the noise dropped. Before QQE, I'd watch RSI flip-flop between overbought and oversold while price just kept grinding sideways — that's where it fell apart for me.

You can find QQE pre-built on TradingView or build your own if you're comfortable with Pine Script. If you're not, tools like Pineify let you generate it without writing code.

Whether you're tired of entering trades by hand or you want to build trading bots that run while you sleep, MQL5 is the language that makes it happen inside MetaTrader 5. MQL5 is a C++-based programming language built directly into MetaTrader 5 for creating Expert Advisors, custom indicators, and automated trading scripts. Once you know it, you can build fully automated systems without any third-party tools or middlemen services.

RSI divergence is a condition where price action and the Relative Strength Index move in opposite directions. When price makes a new high but RSI stalls at a lower high, or when price drops to a fresh low while RSI forms a higher low, the two signals disagree. I've watched this pattern flash on AAPL weekly charts more times than I can count — the stock prints a lower low, RSI refuses to confirm, and within a handful of bars the trend has reversed.

On TradingView, automated indicators do the scanning for you. They flag those mismatches between price and momentum so you don't have to inspect every peak and trough manually. Paired with a thorough Backtest Indicator TradingView: Complete Guide to Testing Your Trading Strategies, they help you decide when a trend is losing steam.

TradingView scripts are custom-built tools created with Pine Script that let traders analyze markets beyond what standard indicators offer. I've been using the platform since 2023, and community scripts are the main reason I stay. Not the built-in RSI or MACD — I can get those on any charting platform. It's the niche tools from creators like ChrisMoody and LazyBear that make the difference.

I watched AAPL jump from 180 to 202 in January 2026. The TTM Squeeze on TradingView caught the compression pattern two days before that move started. The squeeze indicator is a volatility gauge that compares Bollinger Bands against Keltner Channels. When the Bollinger Bands contract inside the Keltner Channels, volatility has dropped to an unusually low level, and that often signals an explosive move is about to begin.

A trading strategy is a fixed set of rules that decides when to enter and exit a trade. If you've spent any time on TradingView, you already know how much firepower it gives you — charts, indicators, a whole community sharing ideas. The thing is, no single indicator will make you profitable. What works is a repeatable plan. I've learned this the hard way: the best strategy on TradingView combines clean technical rules with strict risk management, and you test it before risking real capital.

Ever wondered if a trading idea would actually hold up in real market conditions? The TradingView Strategy Tester is a built-in backtesting engine that simulates how a Pine Script strategy performs against historical data. You get a full performance report with every simulated trade — entry price, exit price, profit, loss — without putting a single dollar at risk. I have run about 60 strategies through this tool over the past three years, and it has caught more bad ideas than I care to admit.
