Pine Script v6 Complete Guide: Build Professional TradingView Indicators

Why Pine Script v6?

Pine Script v6 (released 2024) brings major improvements over v5:

• Better type system
• Improved array and matrix operations
• request.security_lower_tf() for intrabar data
• Better error messages
• Native polyline drawings

If you're still on v5, upgrade now. The syntax is mostly compatible but v6 adds powerful new tools.

Your First Indicator: Structure

****`pine
//@version=6
indicator("My First Indicator", overlay=true, max_lines_count=200, max_boxes_count=200)

// ─── Inputs ─────────────────────────────────────────────────────
int ema_fast = input.int(20, "Fast EMA", minval=1, maxval=200)
int ema_slow = input.int(50, "Slow EMA", minval=1, maxval=200)
color bull_col = input.color(color.new(#26a69a, 0), "Bullish color")
color bear_col = input.color(color.new(#ef5350, 0), "Bearish color")

// ─── Calculations ─────────────────────────────────────────────
float fast = ta.ema(close, ema_fast)
float slow = ta.ema(close, ema_slow)

bool bull_cross = ta.crossover(fast, slow)
bool bear_cross = ta.crossunder(fast, slow)

// ─── Plots ────────────────────────────────────────────────────
plot(fast, "Fast EMA", bull_col, 2)
plot(slow, "Slow EMA", bear_col, 2)

plotshape(bull_cross, "Bull Signal", shape.triangleup, location.belowbar, bull_col, size=size.small)
plotshape(bear_cross, "Bear Signal", shape.triangledown, location.abovebar, bear_col, size=size.small)

Multi-Timeframe Analysis (MTF)

The most powerful feature in Pine Script — pulling data from higher timeframes:

****`pine
//@version=6
indicator("MTF Dashboard", overlay=false)

// Get RSI from multiple timeframes
float rsi_5m = request.security(syminfo.tickerid, "5", ta.rsi(close, 14))
float rsi_15m = request.security(syminfo.tickerid, "15", ta.rsi(close, 14))
float rsi_1h = request.security(syminfo.tickerid, "60", ta.rsi(close, 14))
float rsi_4h = request.security(syminfo.tickerid, "240", ta.rsi(close, 14))
float rsi_1d = request.security(syminfo.tickerid, "D", ta.rsi(close, 14))

// Plot all on same chart
plot(rsi_5m, "RSI 5m", color.new(color.white, 40), 1)
plot(rsi_15m, "RSI 15m", color.yellow, 1)
plot(rsi_1h, "RSI 1H", color.orange, 2)
plot(rsi_4h, "RSI 4H", color.red, 2)
plot(rsi_1d, "RSI 1D", color.purple, 3)

hline(70, "OB", color.new(color.red, 50), linestyle=hline.style_dashed)
hline(30, "OS", color.new(color.green, 50), linestyle=hline.style_dashed)
****`

Pro tip: Use lookahead=barmerge.lookahead_off (the default) to avoid repainting. Never use lookahead_on in a live trading indicator.

Building Dashboard Tables

Tables are the most impressive feature for clients — a full dashboard in the corner of the chart:

****`pine
//@version=6
indicator("Market Dashboard", overlay=true)

// ─── Trend Analysis ────────────────────────────────────────────
string getTrend(int tf) =>
float ma = request.security(syminfo.tickerid, str.tostring(tf), ta.ema(close, 200))
float px = request.security(syminfo.tickerid, str.tostring(tf), close)
px > ma ? "BULLISH" : "BEARISH"

// ─── Create Table ──────────────────────────────────────────────
var table t = table.new(position.top_right, 3, 7,
bgcolor=color.new(color.black, 15),
border_width=1,
border_color=color.new(color.white, 70))

if barstate.islast
// Header
table.cell(t, 0, 0, "TF", text_color=color.white, text_size=size.small, bgcolor=color.new(color.gray, 30))
table.cell(t, 1, 0, "TREND", text_color=color.white, text_size=size.small, bgcolor=color.new(color.gray, 30))
table.cell(t, 2, 0, "RSI", text_color=color.white, text_size=size.small, bgcolor=color.new(color.gray, 30))

int[]    tfs   = array.from(5, 15, 60, 240, 1440)
string[] names = array.from("5m", "15m", "1H", "4H", "1D")

for i = 0 to 4
    int    tf     = array.get(tfs, i)
    string name   = array.get(names, i)
    string trend  = getTrend(tf)
    float  rsi    = request.security(syminfo.tickerid, str.tostring(tf), ta.rsi(close, 14))

    color  tColor = trend == "BULLISH" ? color.new(#26a69a, 0) : color.new(#ef5350, 0)
    color  rColor = rsi > 70 ? color.red : rsi < 30 ? color.green : color.white

    table.cell(t, 0, i+1, name,                   text_color=color.white, text_size=size.small)
    table.cell(t, 1, i+1, trend,                  text_color=tColor, text_size=size.small)
    table.cell(t, 2, i+1, str.tostring(rsi, "#"), text_color=rColor, text_size=size.small)

Order Blocks Detection

****`pine
//@version=6
indicator("Order Blocks", overlay=true, max_boxes_count=50)

int lookback = input.int(5, "Lookback", minval=2, maxval=20)
color bull_ob = input.color(color.new(#26a69a, 80), "Bullish OB")
color bear_ob = input.color(color.new(#ef5350, 80), "Bearish OB")

// Bullish OB: last bearish candle before strong bullish impulse
bool bull_impulse = close > ta.highest(high, lookback)[1]
bool bear_candle = close[1] < open[1]

if bull_impulse and bear_candle
box.new(bar_index[1], high[1], bar_index + 20, low[1],
bgcolor=bull_ob,
border_color=color.new(#26a69a, 40),
border_width=1,
xloc=xloc.bar_index)

// Bearish OB: last bullish candle before strong bearish impulse
bool bear_impulse = close < ta.lowest(low, lookback)[1]
bool bull_candle = close[1] > open[1]

if bear_impulse and bull_candle
box.new(bar_index[1], high[1], bar_index + 20, low[1],
bgcolor=bear_ob,
border_color=color.new(#ef5350, 40),
border_width=1,
xloc=xloc.bar_index)

Connecting to Execution via Webhooks

This is where Pine Script becomes a complete trading system:

****pine // Create an alert condition alertcondition(bull_impulse and bear_candle, title="Bullish OB Formed", message='{"symbol":"{{ticker}}","action":"buy","price":{{close}},"tf":"{{interval}}","time":"{{time}}"}') ****

Then in TradingView:

1. Create Alert → select this indicator
2. Webhook URL → your execution server (n8n, custom Python, etc.)
3. The JSON message gets sent to your server
4. Your server places the trade automatically

---

Performance Optimization

Pine Script runs on every bar — optimization matters:

****`pine
// SLOW: recalculates on every bar
float bad_example = ta.ema(request.security(syminfo.tickerid, "D", close), 200)

// FAST: calculate once, cache result
float htf_close = request.security(syminfo.tickerid, "D", close)
float good_example = ta.ema(htf_close, 200)

// EVEN BETTER: only draw on last bar
if barstate.islast
label.new(bar_index, high, "Today's EMA200: " + str.tostring(good_example, "#.##"))
****`

Publishing Your Indicator on TradingView

Once your indicator is ready:

1. Pine Editor → Save As → choose "Publish"
2. Set to "Public" or "Invite Only" for paid access
3. Write a compelling description with screenshots
4. Price it at $15-$79/month for invite-only

I've seen simple but well-documented indicators earn $1,000-$5,000/month on TradingView's marketplace.
