看不太懂 amibroker 的說明 SetPositionSize

kuolung

網站上的說明是

method (ARRAY) defines how 'size' is interpreted

• spsValue (=1) - dollar value of size (as in previous versions)
• spsPercentOfEquity (=2) - size expressed as percent of portfolio-level equity (size must be from ..100 (for regular accounts) or .1000 for margin accounts)
• spsShares (=4) - size expressed in shares/contracts (size must be > 0 )
• spsPercentOfPosition (=3) - size expressed as percent of currently open position (for SCALING IN and SCALING OUT ONLY)
• spsNoChange (=0) - don't change previously set size for given bar
  

如果，我要設定每次都固定下 一 口單，如何設定

是  

SetPositionSize( 1, spsValue) ; 嗎 ??  好像不是，因為是 spsValue 是 dollar value ;

fattcs

SetPositionSize(1, spsShares);
