50/200 SMA Cross Daily with entry requiring Green MACD Histogram

[brianqw]

I have much experience writing and debugging Excel VBA script, but no experience with thinkscript. I have had Copilot AI write studies for 50/200 SMA Cross with various different filters, but it didn't work, even after much more collaboration with Copilot. Can anyone please give me working thinkscript for 50/200 SMA cross and better yet adding the condition that the MACD histogram be green to take the signal?

Thanks much for any help offered!

Hi Brian,
This script plots green arrows when the 50 SMA crosses above the 200 SMA and the MACD histogram is positive, and red arrows when the 50 SMA crosses below the 200 SMA and the MACD histogram is negative.

declare upper;

# Inputs
input shortSMA_length = 50;
input longSMA_length = 200;
input macd_fastLength = 12;
input macd_slowLength = 26;
input macd_macdLength = 9;

# Calculate SMAs
def shortSMA = simplemovingavg(close, shortSMA_length);
def longSMA = simplemovingavg(close, longSMA_length);

# Calculate MACD components
def macdValue = MovingAverage(AverageType.EXPONENTIAL, close, macd_fastLength) - MovingAverage(AverageType.EXPONENTIAL, close, macd_slowLength);
def signal = MovingAverage(AverageType.EXPONENTIAL, macdValue, macd_macdLength);
def macdHist = macdValue - signal;

# Detect SMA Crosses
def crossAbove = shortSMA crosses above longSMA;
def crossBelow = shortSMA crosses below longSMA;

# Condition: MACD Histogram color
def macdGreen = macdHist > 0;
def macdRed = macdHist < 0;

# Signals with MACD histogram color filter
def buySignal = crossAbove and macdGreen;
def sellSignal = crossBelow and macdRed;

# Plot SMAs
plot SMA50 = shortSMA;
SMA50.SetDefaultColor(Color.CYAN);
plot SMA200 = longSMA;
SMA200.SetDefaultColor(Color.ORANGE);

# Plot buy/sell arrows on price chart
plot BuyArrow = if buySignal then low else Double.NaN;
BuyArrow.SetPaintingStrategy(PaintingStrategy.ARROW_UP);
BuyArrow.SetDefaultColor(Color.GREEN);
BuyArrow.SetLineWeight(3);

plot SellArrow = if sellSignal then high else Double.NaN;
SellArrow.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);
SellArrow.SetDefaultColor(Color.RED);
SellArrow.SetLineWeight(3);

I hope this is what you were looking...
If not, just say the word and I’ll be happy to help you tweak it!
