DCA Buy Alert Script for Long-Term Investors

Hello, TradingView traders!
I'm sharing a simple Pine Script for cautious DCA (Dollar-Cost Averaging) entries.
This script helps accumulate only on weakness — no buying blindly. (Use only on high volatility altcoins!)

🔍 Strategy logic:
• RSI < 40 → market is oversold
• Price below EMA 21 → short-term trend is down
• Price below SMA 200 → long-term trend is weak
Only when ALL three conditions are met, the script triggers a BUY alert.

✅ How to use:
1. Add the script to your chart
2. Create an alert: choose “Cautious DCA Buy Signal”
3. You’ll get notified when the market dips into a DCA zone

//@version=6
indicator("Cautious DCA on Dips", overlay=true)

rsi = ta.rsi(close, 14)
sma = ta.sma(close, 200)
ema = ta.ema(close, 21)

buySignal = rsi < 40 and close < sma and close < ema

plotshape(buySignal, title="Buy Signal", location=location.belowbar, style=shape.labelup, size=size.normal, color=color.green, text="Buy", textcolor=color.white)
plot(sma, title="SMA 200", color=color.orange)
plot(ema, title="EMA 21", color=color.blue)

alertcondition(buySignal, title="Buy Alert", message="DCA Buy Signal: RSI is low and price is below EMA and SMA")

🔔 This script reduces noise and waits patiently for real dips.
Useful for long-term investors who want to buy with discipline.

Let me know how it works for your strategy!
