How Are the Lines Calculated?

RSI Price Line (Green Line)

RSI is the Relative Strength Index line calculated using the RSI Period. And Price Line is an SMA(2) of the RSI.

TSL (Red Line):

It is the Moving Average of past RSI values.

Volatility Bands (Blue):

Top Band = (MA + (1.6185 * StDev(RSI, Volatility Band Period)))

Bottom Band = (MA – (1.6185 * StDev(RSI, Volatility Band Period)))

MBL (Yellow Line):

Average of the volatility Bands:

((Upper Band + Lower Band)/2)

TDI Line Colors:

Volatility Band High (VB HIGH), color: SkyBlue, buffer: UpZone

Volatility Band Low (VB LOW), color: SkyBlue, buffer: DnZone

RSI PRICE LINE, color: Green, buffer: MaBuf

MARKET BASE LINE, color: Yellow, buffer: MdZone

TRADE SIGNAL LINE, color: Red, buffer: MbBuf

TDI Signals:

Strong Buy: PL>TRADE SIGNAL LINE AND TRADE SIGNAL LINE> MARKET BASE LINE AND PL>RSI_OversoldLevel AND PL<RSI_OverboughtLevel

Medium Buy: PL>TRADE SIGNAL LINE AND PL> MARKET BASE LINE AND TRADE SIGNAL LINE< MARKET BASE LINE AND PL>RSI_OversoldLevel AND RSI<RSI_OverboughtLevel

Weak Buy: PL>TRADE SIGNAL LINE AND TRADE SIGNAL LINE<MARKET BASE LINE AND PL< MARKET BASE LINE AND PL>RSI_OversoldLevel AND RSI<RSI_OverboughtLevel

Strong Sell: PL<TRADE SIGNAL LINE AND TRADE SIGNAL LINE< MARKET BASE LINE AND PL>RSI_OversoldLevel AND PL<RSI_OverboughtLevel

Medium Sell: PL<TRADE SIGNAL LINE AND PL< MARKET BASE LINE AND TRADE SIGNAL LINE> MARKET BASE LINE AND PL>RSI_OversoldLevel AND RSI<RSI_OverboughtLevel

Weak Sell: PL<TRADE SIGNAL LINE AND TRADE SIGNAL LINE> MARKET BASE LINE AND PL> MARKET BASE LINE AND PL>RSI_OversoldLevel AND RSI<RSI_OverboughtLevel

HIGH LEVEL CAUTION (Overbought): PL>=RSI_OverboughtLevel

LOW LEVEL CAUTION (Oversold): PL<=RSI_OversoldLevel

TDI Trend:

Strong Up: TRADE SIGNAL LINE>MARKET BASE LINE

Weak Up: TRADE SIGNAL LINE>MARKET BASE LINE AND PL<MARKET BASE LINE

Strong Down: TRADE SIGNAL LINE<=MARKET BASE LINE

Weak Down: TRADE SIGNAL LINE<=MARKET BASE LINE AND PL>=MARKET BASE LINE

Consolidation: VB HIGH-VB LOW<VB_ConsolidationLevel
