Welcome to the Snow Roller automated currency trading system for forex. Snow Roller is designed as a fully automated trading strategy and uses money management to close a basket of fx symbols based on P&L criteria that you enter. Your results depend on the currencies you choose, the timeframe, and the settings (basket profit/loss, symbol profit/loss, position profit/loss). I have provided the source code, your role is to provide the test results, whether good, bad or ugly.

This system is an expansion on 7Bit's "snowballs and the anti-grid" concept. You can find 7Bit's thread here. This basic anti-grid concept has been developed into a fully automated currency trading strategy. MQ4 (MetaTrader) Source code for Snow Roller is available. (see link below)

Basket_Stats: I have created an additional indicator tool to be used with the Snow Roller EA. It will tell you which pairs in your basket are adding to performance, and which pairs are costing you money. You can find the indicator Basket Stats at the link below.

As with all new strategies - please don't trade this strategy with real money until you have fully tested it for several months. I'm making this EA available to encourage testing and feedback / collaboration. I believe this EA has a sound fundamental basis because it's based on the same key concept as the snowball EA but only time and testing will tell how well this formulation performs. If the selected markets trend, Snow Roller should rack up the pips! Testing starts now.

Pairs being tested: EURUSD, USDJPY, GBPUSD, USDCHF, AUDUSD, EURJPY, EURGBP, AUDJPY, CHFJPY, GBPCHF, EURCHF
Timeframe: 5 Minute. Settings - OOTB
Pairs that didn't test well: USDCAD, GBPJPY (YMMV)

For 1 minute the pairs that have tested well: EURJPY, CHFJPY, USDCHF, EURUSD, EURCHF, EURGBP. and GBPUSD is on the bubble.

Let the fun begin!

Download the source code here.

below are some useful scripts:

For those of you using MIG or another br0ker that uses 0.1 minimum lot sizing, I attached my MIG settings file below. Same as the other settings, just changed BalancePerlotsize = 5000.0. Copy file into /experts/presets/ directory and remove .txt from the end of the file.

The discussion of the current formulation starts on post # 106

So far so good - floating with a small loss - this is typical. The OOTB default is set to 100 MaxTrades which limits the total number of trades for the entire basket (all currencies). I'm demoing a small ($500) account using micro lots (0.01 lotsize) on 10 symbols and even with 100 trades there is still plenty of margin left. The system will take off trades to free up margin when the trend indicator for the symbol says to go the opposite direction. I'm off to bed.

Nice!

Will follow with great interest.

Personally, i like EURUSD, EURJPY and EURGBP for their trending nature.

Hi FXEZ,

Do you have a set file to start with?

I know it's kind of hard to determine one but at least i will have some direction in demoing the EA.

Or can you explain the settings in the EA?

Many thanks.

Cam,

I had a similar issue with 7bit's EA. I was using a lot size too small for my broker. Maybe the same with yours?

Snowballer worked perfectly OOTB.

MIG's minimum lot size is 0.1 which i have adjusted accordingly as shown in the set file. Still no action yet.

By the way, i saw OOTB in the first post. What is it exactly? Is it the default settings of the EA?

Have done so, only change the starting lot size and minimum lot size to MIG's requirement, still no action ... ...

I downloaded and installed MIG bank's demo. I had to alter the settings file in two places to make it work due to the fact that MIG bank's smallest lot size is 0.1 instead of 0.01. Here is a settings file that "should work" with brokers of this type.
Here were the changes:
Inserted Code
lotsize=0.10000000
MinLotSize=0.10000000

If your broker uses 0.01 lot sizing, the default settings should do the trick. (actually looking at it MinLotSize isn't used and is now taken out on the website download).

However, there is an additional gotcha, if your broker uses 4 digits or 2 digits (as MIG does for some of its pairs).

Inserted Code
extern int buysellstep =      50;
extern int stoplevel =        200;

If your broker is using 4 or 2 decimal points, the above two lines need to be adjusted to 5 and 20 for a 5 pip entry step, and a 20 pip threshold on exiting losing trades respectively. If your broker uses 0.1 minimum lot sizing, the below settings file should allow trading to begin. Also make sure the Expert Advisors are enabled (large button at top of screen depressed) or Tools/Options/Expert Advisors as shown in the picture:

I have changed the settings accordingly to your suggestions.

It works for EURUSD. However, no action for EURJPY and EURGBP using the same settings.

Do i need to change the magic number for each different pair (i did change)?

What does "Do oppisite" do?

EDIT: It works for EURJPY now but not EURGBP. My guess is that the EA needs time to decide to buy or sell.

No the magic number needs to be the same for the basket closes to work correctly. Double check on each chart (F7) that enable live trading is checked and "Long and Short" positions are enabled. I have a trade on EURJPY now on MIG. Do opposite opens the trades opposite the bar pattern "the trend" which is a 50 bar vs. a 100 bar close for up/down.

Inserted Code
bool uptrend = Close[50] > Close[100];
bool downtrend = Close[50] < Close[100];

What's your consensus if turn on this feature?

Edit: Still waiting for trades to trigger on EURGBP

Edit 2: Finally, EA is working on EURGBP

Regarding the do Opposite feature if the markets are more rangebound this will tend to perform better. If the markets trend doOpposite = false should do best.

Inserted Code
extern double lotsize =       0.01;  // if your broker uses 0.1 minimum lotsize this needs to be changed
extern int MagicNumber =      0;   // used for "CloseAllLoss/CloseAllProfit"
extern int Slippage =         5000;  // set this to an appropriate level for your broker
extern string comment =       "Snow Roller";  // comment to your broker when trade is initiated
extern int CloseAllProfit =   10;  // the following 4 lines are in Dollars or your underlying currency (not pips)
extern int CloseAllLoss =     250;  // basket closure - loss
extern int CloseThisProfit =  10;   // profit closure for this symbol only
extern int CloseThisLoss   =  250; // loss closure for this symbol only
extern int takeprofit =       0; // Single position take profit
extern int stoploss =         0; // Single position stop loss
extern bool doOpposite =      false; // take opposite trades to the trend pattern?
extern int MaxTrades =        100;  // no new trades for all symbols will open past this level
extern int buysellstep =      50;  // 50 = 5 pips for a 3/5 decimal place broker
extern int stoplevel =        200; // 200 = 20 pips for a 3/5 decimal place broker

Hopefully the comments above will make it easier to understand the settings.

Something else I just noticed with MIG is because it uses 0.1 minimum lot sizes, the profits and losses add up way faster. So the CloseALL and CloseThis lines probably need to also be increased by a factor of 10 to allow for decent profits to be accumulated.

I use 100 for profit and 200 for loss for both CloseAll and CloseThis.

P.S. If a pair is Long and closed for loss, will EA open Sell for new trade?

It will if the trend condition says it is a downtrend. When trend condition changes to down and your pair is long, it will start to exit positions 2 at a time until it gets flat then goes long. This can take some time.
