🌲 #newfeature Compiler warnings Warning messages are now issued in certain circumstances when you add a script to a chart. This is one example, for cases where you initialize a new instance of a global variable in a local scope with = instead of assigning the global scope variable a new value using :=. We called those "silent killers" because they were rarely intentional, yet sometimes difficult to spot when debugging code.
Here is an example of code that will generate a warning when you add it to a chart:
//@version=4 study("") a = 1 if close > open a = 2 plot(a)
In this case, variable a will never plot with a value of 2 because it is initialized in the if statement's local scope and disappears from view when the block ends. The coder's intention would have required, instead:
//@version=4 study("") a = 1 if close > open a := 2 plot(a)

The lead from Wall Street offers little clarity as the major averages opened lower on Friday and then bounced back and forth across the unchanged line, finally finishing mixed and little changed.The Dow added 33.18 points or 0.10 percent to finish at 34,798.00, while the NASDAQ eased 4.54 points or 0.03 percent to close at 15,047.70 and the S&P 500 rose 6.50 points or 0.15 percent to end at 4,455.48. For the week, the Dow rose 0.6 percent, the NASDAQ added 0.1 percent and the S&P gained 0.5 percent.The lackluster performance on Wall Street came on uncertainty about the outlook for the markets following recent volatility.
What Is Bitcoin?
Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin’s creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.” Each and every Bitcoin transaction that’s ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. That’s by design: Core to their decentralized nature, Bitcoins aren’t backed by the government or any issuing institution, and there’s nothing to guarantee their value besides the proof baked in the heart of the system. “The reason why it’s worth money is simply because we, as people, decided it has value—same as gold,” says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
