Signals

HaasScript uses signals to indicate when to execute certain actions such as buying, selling, exiting a position, or doing nothing. Signals are represented as an enumerator in HaasScript, and are used in combination with conditional statements to execute trades.

Here are the signals available in HaasScript:

• SignalBuy or SignalLong: Indicates a signal to buy or go long on a position.
• SignalSell or SignalShort: Indicates a signal to sell or go short on a position.
• SignalExitLong: Indicates a signal to exit a long position.
• SignalExitShort: Indicates a signal to exit a short position.
• SignalExitPosition: Indicates a signal to exit any position, regardless of whether it is a bought, sold, long or short position.
• SignalNone: Indicates a signal for “do nothing”.
• SignalError: Indicates a signal error.
• SignalReservedA: A reserved signal used in remote signals.
• SignalReservedB: A reserved signal used in remote signals.

To use signals in HaasScript, you can trigger a trade directly using DoSignal or create a conditional statement that checks for the signal value and execute the corresponding action. For example:

-------------------
-- Direct action
DoSignal( signal )

-------------------
-- Advanced actions
if signal == SignalBuy then
  -- Execute buy action
elseif signal == SignalSell then
  -- Execute sell action
elseif signal == SignalExitPosition then
  -- Execute exit position action
elseif signal == SignalNone then
  -- Do nothing
else
  -- Handle signal error
end

You can also directly input the signal(s) to certain commands, such as GetUnanimousSignal, GetConsensusSignal and GetWeightedConsensusSignal. For example:

signal1 = SignalLong
signal2 = SignalLong
signal3 = SignalShort

unanimousSignal = GetUnanimousSignal(signal1, signal2, signal3)
consensusSignal = GetConsensusSignal(signal1, signal2, signal3)

Log(unanimousSignal) -- output: SignalNone
Log(consensusSignal) -- output: SignalLong

Signals can be used in combination with other indicators or strategies to create more complex trading algorithms. Understanding how to use signals effectively is a key aspect of trading with HaasScript.
