Hi friends,

Please if any kind souls could help or guide the following questions in bold?

# Using engulfing for Long and Short
input length = 20;
input trendSetup = 3;
def BodyMax = Max(open, close);
def BodyMin = Min(open, close);
def IsEngulfing = BodyMax > BodyMax[1] and BodyMin < BodyMin[1];
def IsWhite = open < close;
def IsBlack = open > close;
def IsPrevDoji = IsDoji(length)[1];

plot longSignal = if IsDescending(close, trendSetup)[1] and (IsBlack[1] or IsPrevDoji) and
IsWhite and IsEngulfing then 1 else 0;

plot shortSignal = if IsAscending(close, trendSetup)[1] and (IsWhite[1] or IsPrevDoji) and IsBlack and IsEngulfing then 1 else 0;

def longStopLoss = lowest( entryPrice(),3 ) == 0; # Stoploss will be triggered based on lowest price of the last 3 bars from the entry price, am I coding this correctly?

def longProfit = longStopLoss*3; # How can I record the stop loss value(Even though it is not triggered) and return the profit target price? This allows the risk/reward ratio of 1:3.

def longExitSignal = if longStopLoss or longProfit then 1 else 0; # the condition will trigger whichever one come first

def longExitPrice = close;

def shortStopLoss = highest( entryPrice(),3 ) == 0; # Stoploss will be triggered based on highest price of the last 3 bars from the entry price, am I coding this correctly?

def shortProfit = shortStopLoss*3; # How can I record the stop loss value(Even though it is not triggered) and return the profit target price? This allows the risk/reward ratio of 1:3.

def shortExitSignal = if shortStopLoss or shortProfit then 1 else 0; # the condition will trigger whichever one come first

def shortExitPrice = close;

Many thanks in advance.

Cheers, Lui.

when there is a buy signal, it finds a new lowest and keeps it until the next buy signal.

Ruby: 
# lowest3atbuy

def bn = barnumber();
def na = double.nan;

# Using engulfing for Long and Short
input length = 20;
input trendSetup = 3;
def BodyMax = Max(open, close);
