The logic behind BF Scalper EA is very simple but effective – the EA uses breakouts of the Bollinger
Bands for entry and exit signals.
Reasonable stop loss levels vary 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.
Recommended timeframe: M15
Supported currency pairs: GBPUSD, EURUSD, EURCHF, EURAUD, GBPCAD, USDCAD,
USDCHF and USDJPY
The default settings are for GBPUSD. I have prepared set files for other supported pairs too. Since I
cannot include them here, please contact me, and I will send them to you.
IMPORTANT: Pay attention to the CTHour1-6 parameters! They are very important! In order to get
proper results, you have to set them correctly according to your broker GMT Offset.
StealthMode true/false – conceal stop loss and take profit levels in program logic making them
invisible to brokers. If you use this mode, the stop loss and take profit orders are not located in the
EmergencyStopDist – 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 than 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.
MinEquity – minimal equity needed for trading.
BandPeriod – Bollinger Bands period.
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.

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 at 21 and 22 GMT.
You absolutely should adapt this hours to your brokers GMT shift. The default values are adapted
for GMT +2 (winter time).
WednesdaySwapFilter true/false – Wednesday swap filter cancels all trades in Wednesday
evening in the direction of the negative swap, if the swap is worse than MaxNegSwapPips
MaxNegSwapPips – minus 0.5 pips seems reasonable threshold.

MinutesBefore – minute time interval before midnight, in which all trading operations will be
MinutesAfter – minute time interval after midnight, in which all trading operations will be
x_MaxSpreadFilter – switch on/off the rollover additional spread filter.

all trading operations. As an example, if the MaxSpread is 6 and x_MaxSpread is 2, all trading
operations will be canceled if the spread exceeds 6×2=12 pips.
RecoveryMode – activate the drawdown recovery. It works when AutoMM > 0.
FixedLots – fixed trading lots when AutoMM = 0.
AutoMM – money management. For example, AutoMM=5 means that the robot will trade with 5%
AutoMM_Max – maximum allowed risk when RecoveryMode is used.
