Fair value gap coding in pinescript?
I have tried to write code but unable to add more functions on it.
//#version=5
indicator('Fair Value Gap Akash Mehto', overlay=true)
boxLength = input.int(title='boxLength', defval=6, group='General', inline='General')
boxTransparency = input.int(title='boxTransparency', defval=85, group='General', inline='General')
bullishFvg = low[0] > high[2]
bearishFvg = high[0] < low[2]
if bullishFvg
box.new(left=bar_index - 2, top=low[0], right=bar_index + boxLength, bottom=high[2], bgcolor=color.new(color.rgb(28, 202, 121), boxTransparency), text="FVG", text_size = "tiny", text_halign = text.align_right, text_color = color.green, border_color=color.new(color.green, boxTransparency))
if bearishFvg
box.new(left=bar_index - 2, top=low[2], right=bar_index + boxLength, bottom=high[0], bgcolor=color.new(color.rgb(240, 46, 46), boxTransparency), text="FVG", text_size = "tiny", text_halign = text.align_right, text_color = color.red, border_color=color.new(color.green, boxTransparency))

You folks helped me with another part of this script and I'm making good progress. However, I'm stuck again.
I added a code to produce a dynamic overbought/oversold line on the indicator. That part works great. Now, I'm wanting to add a plotshape when conditions are met to signal long or short. Unfortunately, I can't figure out how to compare a bool variable and a float variable. The dynamic OB/OS lines are floats. The crossover lines are bool.
What I want is for the (green/long) shape to plot when a crossover happens below the dynamic oversold line and the (red/short) shape to plot when the crossunder happens above the dynamic overbought line.
I've tried all kinds of things (var, loop with "while" using sb value as a trigger). I either break the code or I get every crossover plotted. Here is what I have that is stable. I took all my junk that didn't work out:

lengthMA = input(34)
lengthSignal = input(9)
//OverBought = input.float(0.1)
//OverSold = input.float(-0.1)
calc_smma(src, len) =>
smma = 0.0
sma_1 = ta.sma(src, len)
smma := na(smma[1]) ? sma_1 : (smma[1] * (len - 1) + src) / len
smma
calc_zlema(src, length) =>
ema1 = ta.ema(src, length)
ema2 = ta.ema(ema1, length)
d = ema1 - ema2
ema1 + d
src = hlc3
hi = calc_smma(high, lengthMA)
lo = calc_smma(low, lengthMA)
mi = calc_zlema(src, lengthMA)
md = mi > hi ? mi - hi : mi < lo ? mi - lo : 0
sb = ta.sma(md, lengthSignal)
sh = md - sb
mda = ta.sma(md, lengthSignal)
OverBoughtLine = ta.highest(sb * 0.5, lengthMA*100)
OverSoldLine = ta.lowest(sb * 0.5, lengthSignal*100)
shsbCrossOver = ta.crossover(md, sb)
shsbCrossUnder = ta.crossunder(md, sb)
//mdc = src > mi ? src > hi ? color.lime : color.green : src < lo ? color.red : color.orange
mdc = color.green
plot(0, color=color.new(color.gray, 0), linewidth=1, title='MidLine')
plot(md, color=mdc, linewidth=2, title='ImpulseMACD', style=plot.style_line)
plot(sh, color=color.rgb(122, 5, 168, 40), linewidth=2, title='ImpulseHisto', style=plot.style_area)
plot(sb, color=color.rgb(255, 255, 255, transp = 40), linewidth=2, title='ImpulseMACDCDSignal')
plot(OverBoughtLine, color=color.new(#f3e032, 0), linewidth=1, title = 'Overbought Line')
plot(OverSoldLine, color=color.new(color.yellow, 0), linewidth=1, title = 'Oversold Line')
plotshape(shsbCrossOver, "LONG", shape.triangleup, location.bottom, color.new(color.green, 0))
plotshape(shsbCrossUnder, "SHORT", shape.triangledown, location.top, color.new(#cd0808, 0))
//ebc = input(false, title='Enable bar colors')
//barcolor(ebc ? mdc : na)
You cannot compare a bool with a float. It doesn't make any sense and it is not legal in pinescript.
What I want is for the (green/long) shape to plot when a crossover
happens below the dynamic oversold line and the (red/short) shape to
plot when the crossunder happens above the dynamic overbought line.
You want to check if the values you use in that crossover is under your dynamic oversold line at the time of crossover.
OverSoldLine = ta.lowest(sb * 0.5, lengthSignal*100)
shsbCrossOver = ta.crossover(md, sb)
is_good = shsbCrossOver and (md < OverSoldLine) and (sb < OverSoldLine)
In below code, I am getting syntax error for plotshape and several for label. Even for max / min i am getting too many arguments. I used label to get the value from intraburst formula as text. Will need help to resolve these.
//#version=4
study("Intraburst", overlay=true)
truemove = abs(open[2] - close) dayTrueHigh = max(high[1], high,
close[2]) dayTrueLow = min(low[1], low, close[2]) dayTrueRange =
dayTrueHigh - dayTrueLow intraburstLevel = truemove / dayTrueRange *
100
if intraburstLevel > 30
plotshape(series=intraburstLevel, text="ON", style=shape.circle, location=location.abovebar, color=color.green, size=size.normal) else
plotshape(series=intraburstLevel, text="OFF", style=shape.circle, location=location.abovebar, color=color.red, size=size.normal)
label = label.new(bar_index=0, yloc=y_top, xloc=xloc.bar_index,
text=tostring(intraburstLevel, "0.00"), size=size.large,
color=color.black) label.location = location.top label.y = y_top
label.x = x_right label.text = tostring(intraburstLevel, "0.00")
In series, use a ternary
Something like that:
plotshape(
intraburstLevel > 30 ? intraburstLevel : na,
text = "ON",
style = shape.circle,
location = location.abovebar,
color = color.green,
size = size.normal)
plotshape(
intraburstLevel <= 30 ? intraburstLevel : na,
text = "OFF",
style = shape.circle,
location = location.abovebar,
color = color.red,
size = size.normal)
and the label
label.new(
bar_index,
close,
tostring (intraburstLevel, "##.00"),
color = color.black,
textcolor = color.white)
So when I try touch the trigger, the thing I'm trying to animate doesn't so the animation, I tried the animation id, anything else, can someone send me a model that has this, it will be nice if you can.
I made this with the gui elements already done u fill in what u need.
local library = {}
local function onClicked(frame, gui)
gui:SetVisible(false)
gui:ClearAllChildren()
end
function library:Create(parent)
local frame = Instance.new("Frame")
frame.Size = UDim2.new(1, 0, 1, 0)
frame.BackgroundColor3 = Color3.new(1, 1, 1)
frame.BorderSizePixel = 0
local gui = Instance.new("TextLabel")
gui.Size = UDim2.new(0, 200, 0, 50)
gui.BackgroundColor3 = Color3.new(0.5, 0.5, 0.5)
gui.Position = UDim2.new(0.5, -100, 0.5, -25)
gui.Text = "Click the Button"

gui.TextXAlignment = Enum.TextXAlignment.Center
gui.TextYAlignment = Enum.TextYAlignment.Center
gui.Font = Enum.Font.SourceSans
gui.TextSize = 24
gui.Parent = frame
local button = Instance.new("TextButton")
button.Size = UDim2.new(0, 50, 0, 25)
button.BackgroundColor3 = Color3.new(1, 0, 0)
button.Position = UDim2.new(0.5, -25, 0.85, 0)
button.Text = "X"
button.TextColor3 = Color3.new(1, 1, 1)
button.Parent = frame
button.MouseButton1Click:Connect(function()
onClicked(frame, gui)
end)
frame.Parent = parent
return frame

I'm trying to make a map of Europe using tmap and the eurostat package.
I want to add a compass and a scale bar to the map. However they don't appear inside the graph, but outside of the map, at the bottom. Does anyone know what I'm doing wrong? I want the compass at the left top of the map, and the scale bar at the right bottom.

I'm new to python and MyHDL so I started by converting old VHDL projects to MyHDL. This project is a vga timer that can accept any width, height, and frequency (given that they actually work with monitors). It doesn't successfully convert to either VHDL or Verilog because of the statements:
h_count.val.max # line 30
v_count.val.max # line 33
I can print their values just fine so they definitely evaluate to integers, but if I replace them with their literal values then it properly converts. I couldn't find anything about this in the myhdl issue tracker, but I don't want to add a false issue because of a newbie's mistake. Is there a proper way to use Signal.val.max or do I just avoid it? Here's the full code:
from myhdl import Signal, intbv, always_comb, always, toVHDL
def vga_timer(clk, x, y, h_sync, v_sync, vidon, width=800, height=600, frequency=72,
left_buffer=0, right_buffer=0, top_buffer=0, bottom_buffer=0):
# load vga constants by resolution

Any miscellaneous advice on my code is also welcome.
You may have found this out by now, but if you want convertible code, you can't use the signal qualities (min, max, number of bits, etc.) in the combinational or sequential blocks. You can use them in constant assignments outside these blocks, though. So if you put these instead of your print statements:
h_counter_max = h_count.val.max - 1
v_counter_max = v_count.val.max - 1
you can use h_counter_max and v_counter_max in your tests on line 30 and 33.
The min, max attributes can be used in the latest version.
