PineScript v2转v5策略结果不一致，如何匹配原v2逻辑？

The root cause of inconsistent results is that your v5 strategy omitted the log transformation and exponential reversion steps present in the v2 version. Below is the corrected implementation to align both versions' logic:

Critical Adjustments: #

• Apply math.log() to the Heikin Ashi close price when the log transform parameter is enabled
• Use math.exp() to revert transformed values back to their original scale for plotting

Corrected PineScript v5 Code: #

//@version=5
strategy("Heikin Ashi Log Transform Strategy", overlay=true, loginput=true)

// Match v2's logtransform input setting
log_transform = input.bool(true, title="Log Transform")

// Fetch Heikin Ashi close price
ha_ticker = heikinashi(syminfo.tickerid)
ha_close = request.security(ha_ticker, timeframe.period, close)

// Apply log transformation (missing in original v5 code)
if log_transform
    ha_close := math.log(ha_close)

// --- Insert your existing strategy logic here ---
// Example: Calculate indicator using transformed HA close
sma_length = input.int(20, title="SMA Length")
sma_val = ta.sma(ha_close, sma_length)

// --- Plot with exponential reversion when needed ---
// Revert to original scale for accurate plotting
plot_ha_close = log_transform ? math.exp(ha_close) : ha_close
plot_sma = log_transform ? math.exp(sma_val) : sma_val

plot(plot_ha_close, color=color.blue, title="HA Close")
plot(plot_sma, color=color.red, title="SMA on HA Close")

Key Checks: #

• Ensure the log_transform input uses the exact boolean value from your v2 strategy
• All calculations that relied on the transformed HA close in v2 must use the modified ha_close variable in v5
• Plotting requires the exponential revert step to match v2's visual output and strategy performance metrics
