Bollinger Bounce Strategy

Hi All

I have been working on a strategy that I got from a Forex website.

I have tested it out and seems to be working pretty well. The problem I am finding with it that I am struggling to define a good exit strategy. Sometime you would like to let it run to maximize profits.

Strategy
EURUSD mini
Initial Capital $100
15 Min timeframe

Look for Tweezer bottom or tweezer tops

Long Entry
Tweezer Bottom
Low< BolingerDown
bullindicator = OPEN[1] > CLOSE [1] AND OPEN < CLOSE

Short Entry
Tweezer Top
High > BollingerUp
bearindicator = OPEN[1] < CLOSE [1] AND OPEN > CLOSE

Results so far have been pretty good from 25 – 10000 ticks.

Like I said I am trying to work on a good exit strategy to maximize profits currently I am using the EMA 20 do define the exit but sometimes it exits too early.

Here is the code any help will be apprecitated

DEFPARAM CumulateOrders = False // Cumulating positions deactivated
DEFPARAM preloadbars = 0


ema20 = ExponentialAverage[20](close)
//ema8 = ExponentialAverage[20](close)
// Conditions to enter long positions
tweezerTop = ABS(High -(High[1]))<= High * 0.0075
tweezerBottom = ABS(Low -(Low[1]))<= Low * 0.0075

bullindicator = OPEN[1] > CLOSE [1] AND OPEN < CLOSE
bearindicator = OPEN[1] < CLOSE [1] AND OPEN > CLOSE
Boll = 20

Boldown = BollingerDown[Boll](close)
Bolup = BollingerUp[Boll](close)


BolliLong = (low < Boldown) and tweezerBottom and bullindicator
Bolishort = (high > Bolup) and tweezerTop and bearindicator

IF NOT LongOnMarket AND BolliLong THEN
BUY 1 CONTRACTS AT MARKET
ENDIF

LongExit = high < ema20

// Conditions to exit long positions
If LongOnMarket AND LongExit THEN
SELL AT MARKET
ENDIF

// Conditions to enter short positions
IF NOT ShortOnMarket and Bolishort THEN
SELLSHORT 1 CONTRACTS AT MARKET
ENDIF

ShortExit = low > ema20
// Conditions to exit short positions
IF ShortOnMarket AND ShortExit THEN
EXITSHORT AT MARKET
ENDIF

SET STOP PLOSS 20
