 In a strong bull trend day (more than 50 bars above MA), 99.5% of the time there are at least 3 bars with L below EMA.
 No matter how strong the trend is, 99.5% of the day it gets to EMA sometime during the day.
 No matter how strong the trend is, 99.5% of the day there is at least one bar closes below the EMA. Example of the 0.5%: 20221122.
 90% of the time the BO phase is followed by a PB, and then a channel(aka SC) or TR, only 10% of the chance the bull BO reverses, usually as a parabolic wedge top. ^{[2]}
 There is 90% chance of at least one swing trade everyday that starts with a good signal bar, typically goes 40% of recent average day's range^{[3]}, has two or more legs, has a reward at least twice the risk, and lasts at least 12 hours.

80%

 The 80/20 Rule: in a trend, 80% of reversal attempt fails; in a TR, 80% of BO attempt fails.^{[4]}
 when big gap down, 85% chance of PB in 1st two hours.
 80% of the time when pullback to EMA comes after 40 or more bars below the EMA, there will be a selloff that will test the low, however only in 20% of the time the SPBRT sells off to far below the old low with the day closing on the low. Example 20221206.

70%

 if a bar is exceptionally bigger than other bars(i.e. surprise bar), 70% chance of MM, especially when it has ok FT (at least doji).^{[5]}^{[6]}
 after 2 or more consecutive big bull bars closing on their highs, and with little overlap, there is 70% chance of at least a MM up^{[7]}.
 probability of success of 70 percent or better (reward has to be at least half as big as risk just to break even):
 Scalps, but since most traders cannot consistently pick trades with a 70 percent chance of success, they should trade a scalp only if the reward is at least as large as the risk. For example, if you believe that a twopoint stop is needed in the Emini, take the trade only if at least a twopoint reward is reasonable^{[8]}.
 if bull is trying to BO above of a triangle, 70% chance of PB to apex of Triangle^{[9]}.
 70% outside down days closes at lower 1/3 of the range, only 20% closes above middle point^{[10]}.

60%

 Probability of success of 60 percent or better (reward has to be at least as big as risk to break even)^{[12]}:
 Buying a high 2 pullback to the moving average in a bull trend.
 Selling a low 2 pullback to the moving average in a bear trend.
 Buying a wedge bull flag pullback in a bull trend.
 Selling a wedge bear flag pullback in a bear trend.
 Buying a breakout pullback from a breakout of a bull flag in a bull trend.
 Selling a breakout pullback from a breakout of a bear flag in a bear trend.
 Buying a high 1 pullback in a strong bull spike in a bull trend, but not after a buy climax.
 Selling a low 1 pullback in a strong bear spike in a bear trend, but not after a sell climax.
 Shorting at the top of a trading range, especially if it is a second entry.
 Buying at the bottom of a trading range, especially if it is a second entry.
 Trend reversals:
 After a strong break of the trend line, look for a reversal after a test of the trend's extreme where there is a good reversal signal bar. Traders are looking to buy a higher low or a lower low at a bottom, or to short a higher high or a lower high at a top.^{[13]}
 Strong final flag reversal.
 Buying a third or fourth push down in a bear stairs pattern for a test of the low of the prior push down.
 Selling a third or fourth push up in a bull stairs pattern for a test of the high of the prior push up.
 Entering using limit orders; this requires more experience reading charts, because the trader is entering in a market that is going in the opposite direction to the trade. However, experienced traders can reliably use limit or market orders with these setups:
 Buying a bull spike in a strong bull breakout at the market or at the close of the bar, or on a limit order at or below the low of the prior bar^{[14]} (entering in spikes requires a wider stop and the spike happens quickly, so this combination is difficult for many traders).
 Selling a bear spike in a strong bear breakout at the market or at the close of the bar, or on a limit order at or above the high of the prior bar (entering in spikes requires a wider stop and the spike happens quickly, so this combination is difficult for many traders).
 Buying a bear breakout at around a measured move, if the breakout is not too strong—for example, if the range is about four points tall in the Emini, buying on a limit order at four points below the range, risking four points, and expecting a test of the breakout point. Only very experienced traders should consider this.
