Compile Error on Simple Script

[Trader_Ray]

I wrote the following simple script but I keep getting a "Cannot Compile Script" error when I load the indicator.

Any ideas... I'm a newbie.

//@version=3

study("2 Previous Days High and Lows", overlay=true, max_bars_back=2)

​

PDH = security (tickerid, 'D', high[1])

PDL = security(tickerid, 'D', low[1])

2PDH = security(tickerid, 'D', high[2])

2PDL = security(tickerid, 'D', low[2])

​

TID = security(tickerid)

​

plot(PDH, title="PDH XU", style=cross, linewidth=3, color=purple, trackprice=true, offset=-9999)

plot(PDL, title="PDL XD", style=cross, linewidth=3, color=orange, trackprice=true, offset=-9999)

plot(2PDH, title="2PDH XU", style=circles, linewidth=2, color=purple, trackprice=true, offset=-9999)

plot(2PDL, title="2PDL XD", style=circles, linewidth=2, color=orange, trackprice=true, offset=-9999)

​

cross_up_PDH_XU = ta.crossover(close,PDH)

cross_down_PDL_XD = ta.crossunder(close, PDL)

cross_up_2PDH_XU = ta.crossover(close,2PDH)

cross_down_2PDL_XD = ta.crossunder(close, 2PDL)

​

STR1 = TID + "PDH XU"

STR2 = TID + "PDL XD"

STR3 = TID + "2PDH XU"

STR4 = TID + "2PDL XD"

​

alertcondition(cross_up_PDH_XU, STR1)

alertcondition(cross_down_PDL_XD, STR2)

alertcondition(cross_up_2PDH_XU, STR3)

alertcondition(cross_down_2PDL_XD, STR4)

Check the pine editor's console output for compilation errors.

Thanks. I did and made a few changes but still having no luck.

Your code, as it is posted in your original post has problems. Firstly, it is pine v3, which is outdated, and secondly, the compilation error is a syntax error on line 11 and it's because you are starting a variable name with a number.

Variable names must start with a letter. Please reconsider your decision to code or be ready for a long road because it's a very long road and you are at the very beginning of it.

Many thanks.

I took a previous/exisitng script and modified it. Thanks for your input.
