Best Free Scalper EA by FXautomater
M1, M5 Asian session
In my opinion, a very interesting thing. Worth the time to try. Here is what he writes(abbreviated):
" It seems that the current market conditions are good for this kind of systems, so if you have a broker with low spreads during the Asian session you can consider trying this system. As far our experience shows the best pairs for this kind of trading are GBPCAD, GBPUSD, EURCHF, USDJPY, EURGBP, USDCAD and USDCHF. EURUSD shows not bad results recently too.
The logic is very simple but effective - the EA uses breakouts of the Bollinger Bands for entry and exit signals. By my opinion the Bollinger Bands is the best technical indicator ever created - Thank you Mr. John Bollinger! During the years I've tried many other indicators and strategies but the Bollinger Bands has proven itself as the best indicator for scalping the market volatility.
Please, bear in mind that the performance of this kind of trading is highly limited by the brokers conditions - do not even think to try it on random brokers - only on well-known ECN brokers with tight spreads.
Reasonable stop loss levels varies between 20 and 60 pips.
You can use small fixed TP between 4-8 pips, or leave the exit logic to take care of the position.
The exit logic is also based on the BB indicator and it will close the trade even on a loss when the price is near or breaks the opposite BB line. This is commanded by the "BandBreakExit" parameter which works best from minus one to plus one-two.
Here are the EA parameters
Magic - magic number - it is extremely important to keep this different for all robots
MaxSpread - maximum allowed spread
TicksTrade - if it is "false" the logic will be executed at the beginning of M1 bar, otherwise it will calculate and trade on a new price tick. The TicksTrade is potentially more profitable, but I prefer to use M1 open for testing and optimizations as this is the only reliable method for EA testing and tuning.
StopLoss - stop loss value in standard 4 digit pips
TakeProfit - take profit value in standard 4 digit pips
BandPeriod - the period of the Bollinger Bands indicator
BandBreakEntry - breakout in 4 digit pips of the BB line to initiate an opposite trade (the value could be negative)
BandBreakExit - breakout in 4 digit pips of the opposite BB line to initiate closing of the existing trade (the value could be negative)
UseTrendFilter - change this to "true" if you want to trade only in the direction of the trend defined by the two MAs below. If you use the trend filter for Asian session scalping you will get higher profit factor, but less trades. Generally, you do not need trend filter for Asian session scalping, but if you want extra safety it will help.
MA_Fast_Period - period of the fast moving average
MA_Slow_Period - period of the slow moving average
MA_Trend_TF - timeframe of both MAs
TimeRestriction - by default this is "true" so the EA will trade only in the hours listed below. If you do not want to use the time filtration, change this parameter to "false".
CTHour1 - 6 - six possible slots for trading hours. Values 0 - 23 activate the slot. Enter a large value like 55 to deactivate the slot. Best results from our experience are achieved 21 and 22 GMT. You absolutely must adapt this hours to your brokers GMT shift. I am using Alpari data for all my tests, because they have the best long-term real history data in the data center. So for Alpari the trading hours are 23 and 0 as the GMT shift is +2 for Alpari.
RecoveryMode - this parameter activates the drawdown recovery. Works when AutoMM>0
FixedLots - fixed trading lots when AutoMM=0
AutoMM - value greater than zero activates proportional money management, as example AutoMM=5 means 0.05 lots at 1000 account.
AutoMM_Max - maximum allowed value of the proportional money management when RecoveryMode is used.
MMTrades - number of history trades on base of which the drawdown of the RecoveryMode function is calculated
RecoveryFactor - drawdown positive compensation in percent of the drawdown
RecoveryMultiplier - trading volume multiplier in RecoveryMode
LossPausePips - pause after loss algorithm - loss in pips
LossPauseHours - pause after loss algorithm - pause in hours after loss greater than LossPausePips
The EA has high spread protection - this is crucial, because if you use limit orders as example you can't control this and you will take some trades with 10 or even 20 pips spread - one such trade will erase the average profit from 10 good trade as the best average expectancy of this type of trading is 2-3 pips in the best case. This is why I am not using limit orders.
The default settings are for GBPUSD and I will try to provide settings for several other pairs. The settings I provide are subjective - they are based on my personal experience and understanding. No one knows which set of settings will work best in future out of the optimization sample in real market conditions. Please, make your own tests and find the best settings for you!
Here are some optimization advises:
- Do not use genetic algorithm
- Optimize 2 parameters at once at most - I optimize only one at a time and look for the most logical value
- Optimize for at least 6 months and at least 200 trades - this is the absolute minimum to avoid curve fitting and get some reasonable parameters which will have at least some chance to be profitable in real conditions.
- Perform at most 5 optimization cycles for all parameters.
- Use reasonable large optimization step - as example if you optimize stop loss, reasonable step would be 5 pips not 1 pips - about 5% of the reasonable optimization range of the parameter.
- I am using M1 open price test for all my EAs - it is good enough.
- I am not using tick tests as they are too unreliable.
And now the fun part:
By using this EA, you acknowledge that you are familiar with all risks and that you are solely responsible for the outcomes of your decisions. I accept no liability whatsoever for any direct or consequential loss arising from the use of this product. It's to be noted carefully in this respect, that past results are not necessarily indicative of future performance.
Finally - please test and share your experience and best settings with the other users!
UPDATE: 12.12.2017 - version 1.1 added with stealth stop loss functionality.
Description of the new parameters from the Wallstreet Forex Robot user guide:
StealthMode true/false: a mode which conceals stoploss and takeprofit levels in program logic, making them invisible to brokers. If you use this mode, the stoploss and takeprofit orders are not located in the trading server. In this case, if your trading terminal is not connected, or the robot is not working, your orders would not be protected. However, we are strongly encouraging using the StealthMode, because in some cases the visible StopLoss levels could be attacked tendentiously by algorithms that some unethical brokers could use.
EmergencyStopDist: this parameter ensures a second level of protection, when StealthMode is used. At values greater than zero it activates a second level of true (Emergency) StopLoss on a greater distance then the virtual hidden StopLoss is located. In such case the value of the new emergency StopLoss will be the sum of the EmergencyStopDist value plus the value of the hidden StopLoss.
UPDATE: 12.18.2017 - version 1.2 added
- Friday filter added
- Wednesday swap filter added
I think the new parameters are clear enough:
== Friday Filter ==
FridayFilter - true/false
FridayEndHour
== Wednesday Swap Filter ==
WednesdaySwapFilter - true/false
MaxNegSwapPips - minus 0.5 pips seems reasonable threshold for me
The Wednesday swap filter cancels all trades in Wednesday evening in the direction of the negative swap, if the swap is worse than MaxNegSwapPips parameter.
I personally do not use the Friday filter as it reduces the profit and the Monday gap is 50/50 for me in long term"
