Filter Indicators: using analysis to enter positions wisely
Introduction to indicators: RSI, MACD, Bollinger Bands and other bot filters
Filter Indicators: Smart Entry
Indicators are mathematical formulas analyzing prices and volume to find favorable entry moments.
What's a Filter?
A filter is a condition allowing bot to buy:
❌ No filter: buy always (every day/week) ✅ With filter: buy only if RSI < 30 (oversold)
Filters help avoid worst entry moments.
8 Main Indicators on AI Traders
1. RSI (Relative Strength Index)

- Signal: line crosses signal line
- Used for: trend confirmation
- Best for: up/downtrends
3. Bollinger Bands (BB)

- Best for: sideways markets
4. ATR (Average True Range)
- Signal: volatility above average

How to Choose an Indicator?
For DCA Strategy
Recommendation: RSI < 30 or Stochastic < 20
- Buy only at bottom
- Skip peaks
For Grid Trading
Recommendation: Bollinger Bands or ATR
- Confirms entries
- Detects volatility
For Long-term Accumulation
Recommendation: EMA or MACD

- Minimizes noise
Combining Indicators
Powerful combo:
- EMA (ensure price above long-term trend)
- RSI < 30 (ensure oversold)
- Volume > average (ensure market interest)
Only if ALL three conditions met — bot buys!
Common Mistake: Too Many Filters
❌ Wrong: buy if RSI < 30 AND MACD crossed AND BB below AND Volume > AND EMA...
- Conditions match rarely
- Bot sits idle for weeks
✅ Right: max 2–3 conditions
- Buys often enough
- Avoids worst entries
First Steps
- Choose one indicator (recommend RSI)
- Set condition (RSI < 30)
- Test in Paper Trading
- Watch results 2–3 weeks
- Add second indicator if results good
