Overview

TEMA + Bollinger Bands Strategy plots the TEMA line along with the Bollinger Bands basis and outer bands. Long entries trigger when RSI crosses below 30, TEMA is below the basis but crosses upward. Long positions close when RSI crosses above 70 or TEMA crosses downward through the basis. Short entries activate under symmetric conditions and close on opposite RSI or TEMA signals. Inputs modify the Bollinger period, TEMA length, RSI length, and band multiplier. The strategy uses no stop loss by default and operates on any market with any timeframe.

• TEMA indicator
• Bollinger Bands
• RSI oscillator
• long short entries
• price chart overlay
