Multi currency EA may be based on some other systems. The only thing to do (except the system itself) is 'account protection feature'. Because those kind of EAs may be risky, and this risk is for whole the account (just my opinion sorry). But it also depends on how it will be coded for example.

The Non Repainting SuperTrend is particularly stable and has a few advantages over older version of SuperTrend indicators:

It uses a moving (statistical) median of the arithmetic mean (High
+ Low)/2 of the bars instead of a moving average. The (statistical)
median is known to be more robust than any average.

It calculates both the Median and the ATR (average true range) 1 bar
ago, whereas the original SuperTrend indicator takes the ATR and moving
average of the current bar. If you use the current bar’s ATR, the
current bar’s breakout is partly measured against its own range. This is
particularly true, if the ATR period is short.

Signals: The Non Repaiting SuperTrend indicator gives a reversal signal, when the bar closes on the other side of the stop line.

This is very easy to understand/estimate the direction of the trend using this indicator (for your manual trading system to open buy or sell trade for example). You can try this indicator to see it by yourself.

Fibonacci Retracements are ratios used to identify potential reversal
levels. These ratios are found in the Fibonacci sequence. The most
popular Fibonacci Retracements are 61.8% and 38.2%. Note that 38.2% is
often rounded to 38% and 61.8 is rounded to 62%. After an advance,
chartists apply Fibonacci ratios to define retracement levels and
forecast the extent of a correction or pullback. Fibonacci Retracements
can also be applied after a decline to forecast the length of a counter
trend bounce. These retracements can be combined with other indicators
and price patterns to create an overall strategy.

The Sequence and Ratios

This article is not designed to delve too deep into the mathematical
properties behind the Fibonacci sequence and Golden Ratio. There are
plenty of other sources for this detail. A few basics, however, will
provide the necessary background for the most popular numbers. Leonardo
Pisano Bogollo (1170-1250), an Italian mathematician from Pisa, is
credited with introducing the Fibonacci sequence to the West. It is as
follows:

The sequence extends to infinity and contains many unique mathematical properties.

After 0 and 1, each number is the sum of the two prior numbers (1+2=3, 2+3=5, 5+8=13 8+13=21 etc…).

A number divided by the previous
number approximates 1.618 (21/13=1.6153, 34/21=1.6190, 55/34=1.6176,
89/55=1.6181). The approximation nears 1.6180 as the numbers increase.

A number divided by the next highest
number approximates .6180 (13/21=.6190, 21/34=.6176, 34/55=.6181,
55/89=.6179 etc….). The approximation nears .6180 as the numbers
increase. This is the basis for the 61.8% retracement.

A number divided by another two
places higher approximates .3820 (13/34=.382, 21/55=.3818, 34/89=.3820,
55/=144=3819 etc….). The approximation nears .3820 as the numbers
increase. This is the basis for the 38.2% retracement. Also, note that 1
- .618 = .382

A number divided by another three
places higher approximates .2360 (13/55=.2363, 21/89=.2359,
34/144=.2361, 55/233=.2361 etc….). The approximation nears .2360 as the
numbers increase. This is the basis for the 23.6% retracement.

1.618 refers to the Golden Ratio or Golden Mean, also called Phi. The
inverse of 1.618 is .618. These ratios can be found throughout nature,
architecture, art and biology. In his book, Elliott Wave Principle,
Robert Prechter quotes William Hoffer from the December 1975 issue of
Smithsonian Magazine:

….the proportion of .618034 to 1 is the mathematical basis for the
shape of playing cards and the Parthenon, sunflowers and snail shells,
Greek vases and the spiral galaxies of outer space. The Greeks based
much of their art and architecture upon this proportion. They called it
the golden mean.

Alert Zones

Retracement levels alert traders or investors of a potential trend
reversal, resistance area or support area. Retracements are based on the
prior move. A bounce is expected to retrace a portion of the prior
decline, while a correction is expected to retrace a portion of the
prior advance. Once a pullback starts, chartists can identify specific
Fibonacci retracement levels for monitoring. As the correction
approaches these retracements, chartists should become more alert for a
potential bullish reversal. Chart 1 shows Home Depot retracing around
50% of its prior advance.

The inverse applies to a bounce or corrective advance after a decline.
Once a bounce begins, chartists can identify specific Fibonacci
retracement levels for monitoring. As the correction approaches these
retracements, chartists should become more alert for a potential bearish
reversal. Chart 2 shows 3M (MMM) retracing around 50% of its prior
decline.

Keep in mind that these retracement levels are not hard reversal points.
Instead, they serve as alert zones for a potential reversal. It is at
this point that traders should employ other aspects of technical
analysis to identify or confirm a reversal. These may include
candlesticks, price patterns, momentum oscillators or moving averages.

Common Retracements

The Fibonacci Retracements Tool at StockCharts shows four common
retracements: 23.6%, 38.2%, 50% and 61.8%. From the Fibonacci section
above, it is clear that 23.6%, 38.2% and 61.8% stem from ratios found
within the Fibonacci sequence. The 50% retracement is not based on a
Fibonacci number. Instead, this number stems from Dow Theory's assertion
that the Averages often retrace half their prior move.

Based on depth, we can consider a 23.6% retracement to be relatively shallow. Such retracements would be appropriate for flags
or short pullbacks. Retracements in the 38.2%-50% range would be
considered moderate. Even though deeper, the 61.8% retracement can be
referred to as the golden retracement. It is, after all, based on the
Golden Ratio.

Shallow retracements occur, but catching these requires a closer watch
and quicker trigger finger. The examples below use daily charts covering
3-9 months. Focus will be on moderate retracements (38.2-50%) and
golden retracements (61.8%). In addition, these examples will show how
to combine retracements with other indicators to confirm a reversal.

Moderate Retracements

Chart 3 shows Target (TGT) with a correction that retraced 38% of the
prior advance. This decline also formed a falling wedge, which is
typical for corrective moves. The combination raised the reversal alert.
Chaikin Money Flow turned positive as the stock surged in late June,
but this first reversal attempt failed. Yes, there will be failures. The
second reversal in mid July was successful. Notice that TGT gapped up,
broke the wedge trend line and Chaikin Money Flow turned positive (green
line).

Chart 4 shows Petsmart (PETM) with a moderate 38% retracement and other
signals coming together. After declining in September-October, the stock
bounced back to around 28 in November. In addition to the 38%
retracement, notice that broken support turned into resistance in this
area. The combination served as an alert for a potential reversal.
William %R was trading above -20% and overbought as well. Subsequent
signals affirmed the reversal. First, Williams %R moved back below -20%.
Second, PETM formed a rising flag and broke flag support with a sharp
decline the second week of December.

Golden Retracements

Chart 4 shows Pfizer (PFE) bottoming near the 62% retracement level.
Prior to this successful bounce, there was a failed bounce near the 50%
retracement. The successful reversal occurred with a hammer on high
volume and follow through with a breakout a few days later.

Chart 5 shows JP Morgan (JPM) topping near the 62% retracement level.
The surge to the 62% retracement was quite strong, but resistance
suddenly appeared with a reversal confirmation coming from MACD
(5,35,5). The red candlestick and gap down affirmed resistance near the
62% retracement. There was a two day bounce back above 44.5, but this
bounce quickly failed as MACD moved below its signal line (red dotted
line).

Conclusions

Fibonacci retracements are often used to identify the end of a
correction or a counter-trend bounce. Corrections and counter-trend
bounces often retrace a portion of the prior move. While short 23.6%
retracements do occur, the 38.2-61.8% covers the more possibilities
(with 50% in the middle). This zone may seem big, but it is just a
reversal alert zone. Other technical signals are needed to confirm a
reversal. Reversals can be confirmed with candlesticks, momentum indicators, volume or chart patterns. In fact, the more confirming factors the more robust the signal.

The Renko charting method is thought to have acquired its name from "renga"
which is the Japanese word for bricks. Renko charts are similar to Three Line Break charts except that in a Renko chart,
a line (or "brick" as they're called) is drawn in the direction of the prior
move only if prices move by a minimum amount (i.e., the box size). The bricks
are always equal in size. For example, in a 5-unit Renko chart, a 20-point rally
is displayed as four, 5-unit tall Renko bricks.

Kagi charts were first
brought to the United States by Steven Nison when he published the book, Beyond Candlesticks.

Interpretation

Basic trend reversals are signaled with the emergence of a new white or black
brick. A new white brick indicates the beginning of a new up-trend. A new black
brick indicates the beginning of a new down-trend. Since the Renko chart is a
trend following technique, there are times when Renko charts produce whipsaws,
giving signals near the end of short-lived trends. However, the expectation with
a trend following technique is that it allows you to ride the major portion of
significant trends.

Since a Renko chart isolates the underlying price trend by filtering out the
minor price changes, Renko charts can also be very helpful when determining
support and resistance levels.

Calculation

Renko charts are always based on closing prices. You specify a "box size"
which determines the minimum price change to display.

To draw Renko bricks, today's close is compared with the high and low of the
previous brick (white or black):

If the closing price rises above the top of the previous brick by at least
the box size, one or more white bricks are drawn in new columns. The height of
the bricks is always equal to the box size.

If the closing price falls below the bottom of the previous brick by at least
the box size, one or more black bricks are drawn in new columns. Again, the
height of the bricks is always equal to the box size.

If prices move more than the box size, but not enough to create two bricks,
only one brick is drawn. For example, in a two-unit Renko chart, if the prices
move from 100 to 103, only one white brick is drawn from 100 to 102. The rest of
the move, from 102 to 103, is not shown on the Renko chart.

Moving Averages can be used with Renko bars with some minor setting changes to pinpoint entries

Seeing the trend without Forex market noise is the goal of every trader.
Too many times, traders get head-faked by the twists and turns of price
action.

In addition moving averages can be used to signal entries and exits as
well. A couple of settings have to be changed in order to get the moving
averages which are usually tied to time, to work with a chart system
that is based on price.

To add a 13-period exponential moving average to the Renko chart, choose
EMA from the Add Indicator menu then change “Number of periods” to 13.

Notice the chart above which displays both Renko bars and a 13-period
exponential moving average. A simple system can be built around the
Renko bars and the moving average. When Renko price bars cross below the
moving average and turns red, traders can enter short and stay with the
trend until the Renko bars cross back above the moving average.

An initial stop could be placed just above the last blue Renko brick.
Keep in mind that in the above example, each brick is equal to five
pips. In the above example, the red circles mark where the Renko bars
crossed below the moving average. A trader can see that a number of pips
could have been gathered as the bars stayed below the moving average.

On the other hand, when the Renko bars change color and cross above the
moving average, traders can enter long placing stop just below the last
red Renko brick. The above chart shows in the green circles, points were
the Renko price bars moved above the moving average generating a clear
buy signal.

Renko charts, without the dimension of time, may take a little getting a
little used to. But once you get the hang of them, you may find it
difficult to go back to the candles. Adding a moving average gives
excellent signals for entry and exit. Marrying them up with other
indicators can magnify the benefits of trading without noise and scary
wicks!
