Hello, There is no bug. If it says that position is not entered because of insufficient funds it means that desired position can't be opened with specified size. Most probably either your formula specifies wrong (too high) size, or your round lot sizing does not allow too small pos, or you don't have "position size shrinking" option enabled. If you have trouble, send the formula to SUPPORT and we will point out the error in your formula.

Hi, I am trying to test the scale in/out in AM5.2, and base the code on the AM tutorial on scalein/out. I found that, sometimes, portfolio backtester doesn't enter a trade, even though there are enough cash. For example, I set the backtester initial fund to 100,000, max 4 open positions, and each position will use 10,000, report to detailed log mode. It is very strange that backtester doesn't enter the trade on some days, like 14/4/09 and shows message. CTV not entered because of insufficient funds But there is 80,514.9 cash available. A trade only needs 10,000 Anyone has seen this issue before? Is it a bug? thanks, Steven Date Information 3/4/2009 Entry signals(score): Exit signals: 0 Open Positions: , Equity: 100000, Cash: 100000 6/4/2009 Entry signals(score):ALV=Buy(68.6973), YRCW=Buy(66.7675), BCS=Buy(64.5193), ACH=Buy(63.5376), BGC=Buy(63.3302), JBL=Buy(62.4348), TIN=Buy(60.5582), FCX=Buy(60.5032), Exit signals: Enter Long, ALV, Price: 22.53, Shares: 440, Commission: 2, Rank: 68.6973, Equity 99996, Margin Loan: 0, Fx rate: 1 Enter Long, YRCW, Price: 5.42, Shares: 1840, Commission: 2, Rank: 66.7675, Equity 99992, Margin Loan: 0, Fx rate: 1 Enter Long, BCS, Price: 10.24, Shares: 970, Commission: 2, Rank: 64.5193, Equity 99988, Margin Loan: 0, Fx rate: 1 Enter Long, ACH, Price: 18.01, Shares: 550, Commission: 2, Rank: 63.5376, Equity 99984, Margin Loan: 0, Fx rate: 1 4 Open Positions: , ALV (+440), , YRCW (+1840), , BCS (+970), , ACH (+550), Equity: 99816.3, Cash: 60267.7 7/4/2009 Entry signals(score):LAMR=Buy(68.0092), CE=Buy(66.6134), ALV=Buy(62.2498), ACH=Buy(59.5062), FCX=Buy(59.2346), BGC=Buy(56.7888), HPT=Buy(55.0469), BX=Buy(53.7648), Exit signals:BCS=Sell, CI=Sell, FRPT=Sell, JBL=Sell, TIN=Sell, YRCW=Sell, Exit Long, YRCW, Price: 5.17, (Avg. exit pr. 5.17), Shares: 1840, Commission: 2, (Total comm.: 4), Profit: -464 (-4.65 %), Entry rank:66.7675, Equity: 98051.8, Fx rate: 1 Exit Long, BCS, Price: 9.468, (Avg. exit pr. 9.468), Shares: 970, Commission: 2, (Total comm.: 4), Profit: -752.84 (-7.58 %), Entry rank:64.5193, Equity: 98051.8, Fx rate: 1 Enter Long, LAMR, Price: 13.72, Shares: 720, Commission: 2, Rank: 68.0092, Equity 97919.8, Margin Loan: 0, Fx rate: 1 Enter Long, CE, Price: 15.6003, Shares: 640, Commission: 2, Rank: 66.6134, Equity 97915.8, Margin Loan: 0, Fx rate: 1 4 Open Positions: , ALV (+440), , ACH (+550), , LAMR (+720), , CE (+640), Equity: 97384.1, Cash: 59093.9 8/4/2009 Entry signals(score):PAY=Buy(66.8912), HOG=Buy(62.6152), ACH=Buy(61.577), BGC=Buy(59.7941), DB=Buy(59.7539), HPT=Buy(57.583), CI=Buy(56.9387), FCX=Buy(56.7986), Exit signals:LEN=Sell, MBI=Sell, XCO=Sell, 4 Open Positions: , ALV (+440), , ACH (+550), , LAMR (+720), , CE (+640), Equity: 98179, Cash: 59093.9 9/4/2009 Entry signals(score):CE=Buy(72.8305), VMED=Buy(72.798), ALV=Buy(70.1462), PAY=Buy(68.8664), HOG=Buy(68.3335), ACH=Buy(65.9337), DB=Buy(65.6035), BGC=Buy(64.8912), Exit signals:ALV=Scale-Out, CE=Scale-Out, CI=Scale-Out, DB=Scale-Out, HOG=Scale-Out, HPT=Sell, M=Sell, PAY=Scale-Out, STT=Sell, WSM=Sell, Scale-Out Long ALV, Price 24.783, Shares 220, Fx Rate 1, Number of shares - Current: 220, Exited: 220, Total Cost: 9913.2, Avg.
