Introduction: As a trader with over 10 years of experience, I've developed and refined various trading strategies. One strategy that I find particularly effective is based on the concept of risk-reward ratio. In this blog post, I'll share a simple yet powerful trading bot that aims for a risk-reward ratio of 1:3.

Understanding Risk-Reward Ratio: The risk-reward ratio is a key concept in trading that compares the potential profit of a trade to the potential loss. A ratio of 1:3 means that for every dollar you risk, you aim to make three dollars in profit. This allows traders to potentially profit even if they're right less than half the time, as long as their winners outpace their losers.

The Trading Strategy: The trading bot we'll be building is based on the risk-reward ratio concept. Here's a breakdown of how it works:

1. Inputs: The user specifies the risk percentage, reward ratio, and stop loss distance.

2. Calculations: The bot calculates the stop loss and take profit levels based on the specified parameters.

3. Strategy Conditions: It enters long positions when the price crosses above the stop loss level and short positions when the price crosses below the stop loss level.

4. Execution: The bot executes trades and sets stop loss and take profit levels accordingly.

The Pine Script Code:

//@version=4
strategy("Risk-Reward Ratio Bot - by Waran Gajan Bilal", overlay=true)

// Define inputs
riskPercentage = input(1, title="Risk Percentage (%)", type=input.float)/100
rewardRatio = input(3, title="Reward Ratio", type=input.integer)
stopLossDistance = input(100, title="Stop Loss Distance", type=input.integer)

// Calculate stop loss and take profit levels
stopLossLevel = close * (1 - riskPercentage)
takeProfitLevel = close * (1 + (rewardRatio * riskPercentage))

// Plot stop loss and take profit levels on the chart
plot(stopLossLevel, title="Stop Loss", color=color.red)
plot(takeProfitLevel, title="Take Profit", color=color.green)

// Strategy conditions
longCondition = crossover(close, stopLossLevel)
shortCondition = crossunder(close, stopLossLevel)

// Execute trades
strategy.entry("Long", strategy.long, when=longCondition)
strategy.entry("Short", strategy.short, when=shortCondition)

// Set stop loss and take profit levels
strategy.exit("Long", "Stop Loss", stop=stopLossLevel, when=longCondition)
strategy.exit("Long", "Take Profit", limit=takeProfitLevel, when=longCondition)
strategy.exit("Short", "Stop Loss", stop=stopLossLevel, when=shortCondition)
strategy.exit("Short", "Take Profit", limit=takeProfitLevel, when=shortCondition)

Conclusion: This trading bot provides a simple yet effective way to implement a risk-reward ratio strategy in your trading. However, remember that no strategy guarantees success, and it's essential to thoroughly backtest and validate any trading strategy before deploying it with real money. Additionally, always practice proper risk management to protect your capital.
