WHAT THE LOW TRIN MEANS
 
Date:  
October 29, 2008
 
Stock, Index, 
Bond or Commodity:  DJIA
 
Summary:  The Arms Index (aka TRIN) closed at 0.20 
yesterday for the NYSE.  This means that there was a made scramble of 
volume into issues that rose on the day.  Low Arms Index readings can 
sometimes signal overbought conditions, but coming out of intermediate-term 
oversold conditions, that's not often the case.
 
Even so, 
exceptionally low Arms Index readings like we saw yesterday, whether or not the 
market was down at the time, show bullish intermediate-term tendencies going 
forward.

Number of 
Trades
The total number of round-trip trades plus open 
positions.
Avg Profit/Loss (In $ if trading a stock or ETF, and in 
points if trading an index)
The average profit/loss per trade in 
dollars.
Avg Profit/Loss %
The average percentage profit/loss 
per trade in percent.
Winning Trades (In Green) and Losing Trades (In 
Red)
A trade is marked a winner if its return after costs is above 
zero.  These sections present the same metrics as above, plus Max 
Consecutive, which is the maximum number of consecutive winners and losers 
generated in a row.
Max Drawdown
Max Drawdown is the largest 
peak to valley dollar decline in the system's equity curve. 
Max 
Drawdown Date
Date on which the Max Drawdown was realized.
 
Net 
Profit
The total profit generated by the trading system.
 
Buy & 
Hold Profit (or points if trading an index)
The total profit one would 
have achieved by simply buying at the beginning of the study period and holding 
until the end, with no trading.  For active systems with many trades, 
compare the net profit against this figure to see if it would have been worth it 
to trade the system, or better to just buy-and-hold.
Profit 
Factor
Profit Factor is the system's Gross Profit divided by Gross Loss. 
Look for systems that have a Profit Factor of 2 or higher.
Recovery 
Factor
Recovery Factor is equal to the absolute value of Net Profit 
divided by Max Drawdown. Recovery Factor should typically be larger than 1. A 
healthy Recovery Factor is an indication that a system can overcome a 
drawdown.
Payoff Ratio
Payoff Ratio is the absolute value of 
the system's average percentage profit per trade divided by the average 
percentage loss per trade. Unless the system has a particularly high Win/Loss 
ratio, we look for high Payoff Ratios.
Ulcer Index
The Ulcer 
Index measures a portfolio's overall volatility. It is calculated by summing the 
squared draw downs, and then taking the square root of the quotient of this sum 
divided by the period. A lower Ulcer Index indicates less volatility and draw 
down, indicating that the system might be easier to tolerate in real-world 
trading.
Luck Coefficient
The Luck Coefficient shows how the 
largest trade compares to the average trade and is calculated by dividing the 
percentage profit of the largest winning trade by the average percentage profit 
of all winning trades. The larger the Coefficient value, the greater portion of 
the system results are attributed to the largest winning trade, or, luck.
