Hi!

I’m a rookie and I’m having trouble to create a code that increases and decreases the number of contracts based on profits/losses.

I need a code that’s increasing contracts by 0.25 for every 350$ profit. So if a single trade profits 700$ that would mean that the system should increase with two steps immediately (increase with 0.5 contracts in this example).

The same if it loses a single trade for 1050$ then it would need to decrease contracts with three steps (0.75 contracts in this example).

I have searched a lot on the forum without finding anything that works the way I want it to. Everything I found does not take into account if a trade make a huge profit or a huge loss, that it need to increase/decrease several steps at once.

If anyone could help me to create this code I would be extremely grateful!

Regards

The rookie

There you go (not tested):

Once MinSize = 0.5      //minimum sizecrequired
Once LotSize = MinSize  //starting size (can be bigger than minimum)
Once LotStep = 250      //increase/decrease this money step
LotSize      = max(MinSize,MinSize + round(StrategyProfit / LotStep) //update LotSize

Once MinSize = 0.5 //minimum sizecrequired

Once LotSize = MinSize //starting size (can be bigger than minimum)

Once LotStep = 250 //increase/decrease this money step

LotSize = max(MinSize,MinSize + round(StrategyProfit / LotStep) //update LotSize

Sorry, line 4 should read:

LotSize = max(
MinSize,MinSize + (MinSize * round(StrategyProfit / LotStep)))

1 2	LotSize = max( MinSize,MinSize + (MinSize * round(StrategyProfit / LotStep)))

Hi to everybody here.

Well, I found this topic and it seems interesting to me. I tried to add it into a strategy running in demo and I got different results on long and short trades.

Then I modified it as follows (just setting different quantities and profit amount for short and long trades) but I can’t find a way to obtain the strategyprofit only for long trades and/or for short ones. Is there any way to know the profit generated by long or short trades ????

// for LONG trades
Once MinSizeL = 1 //minimum sizecrequired
Once LotSizeL = MinSizeL //starting size (can be bigger than minimum)
Once LotStepL = 250 //increase/decrease this money step
LotSizeL = max(MinSizeL,MinSizeL + (MinSizeL * round(StrategyProfit / LotStepL)))
myLotL=LotSizeL

// for SHORT trades
Once MinSizeS = 1 //minimum sizecrequired
Once LotSizeS = MinSizeS //starting size (can be bigger than minimum)
Once LotStepS = 250 //increase/decrease this money step
LotSizeS = max(MinSizeS,MinSizeS + (MinSizeS * round(StrategyProfit / LotStepS)))
myLotS=LotSizeS

Many thanks !!!!!!!!!!!!!

This snippet should to, to split STRATEGYPROFIT into two parts, Long and Short performances (not tested):

ONCE LongProfit  = 0
ONCE ShortProfit = 0
IF StrategyProfit <> StrategyProfit[1] THEN
   IF LongOnMarket[1] THEN
      LongProfit  = LongProfit  + (StrategyProfit - StrategyProfit[1])
   ELSIF ShortOnMarket[1] THEN
      ShortProfit = ShortProfit + (StrategyProfit - StrategyProfit[1])
   ENDIF
ENDIF

ONCE LongProfit = 0

ONCE ShortProfit = 0

IF StrategyProfit <> StrategyProfit[1] THEN

IF LongOnMarket[1] THEN

LongProfit = LongProfit + (StrategyProfit - StrategyProfit[1])

ELSIF ShortOnMarket[1] THEN

ShortProfit = ShortProfit + (StrategyProfit - StrategyProfit[1])

ENDIF

@ rOBERTO

many thanks for your prompt answer.

I’m testing it but it seems to work unproperly.

At the end of the backtest i’ll send here the complete system for your comments.

Thanks !!

There was an issue when a single-bar trade occurred, with this modification everything seems to work fine (tested on DAX, Daiky TF):

ONCE LongProfit  = 0
ONCE ShortProfit = 0
IF StrategyProfit <> StrategyProfit[1] AND BarIndex > 0 THEN
   Profitto = StrategyProfit - StrategyProfit[1]
   IF LongOnMarket[1] THEN
      LongProfit  = LongProfit  + Profitto
   ELSIF ShortOnMarket[1] THEN
      ShortProfit = ShortProfit + Profitto
   ELSE
      p1 = 1
      p2 = 2
      IF OnMarket THEN
         p1 = 2
         p2 = 3
      ENDIF
      IF TradePrice(p1) > TradePrice(p2) THEN
         IF Profitto > 0 THEN
            LongProfit  = LongProfit  + Profitto
         ELSE
            ShortProfit = ShortProfit + Profitto
         ENDIF
      ELSIF TradePrice(p1) < TradePrice(p2) THEN
         IF Profitto < 0 THEN
            LongProfit  = LongProfit  + Profitto
         ELSE
            ShortProfit = ShortProfit + Profitto
         ENDIF
      ELSE
         LongProfit  = LongProfit  + (Profitto / 2)
         ShortProfit = ShortProfit + (Profitto / 2)
      ENDIF
   ENDIF
ENDIF

elsif close crosses under average[200,0](close) then
   sellshort at market

Dear ROBERTO,

many thanks for spending your time about this issue. I will try your new system but I think is missing the part regarding the definition of buy/sell number of contracts . Here below I added a part of your previous reply to let the system calculate the contract q.ty based on profit levels (SEE BOLD WORDS). Do you think it’s OK in this way ????

ONCE LongProfit = 0

ONCE ShortProfit = 0

IF StrategyProfit <> StrategyProfit[1] AND BarIndex > 0 THEN

Profitto = StrategyProfit – StrategyProfit[1]

IF LongOnMarket[1] THEN

LongProfit = LongProfit + Profitto

ELSIF ShortOnMarket[1] THEN

ShortProfit = ShortProfit + Profitto

ELSE

p1 = 1

p2 = 2

IF OnMarket THEN

p1 = 2

p2 = 3

ENDIF

IF TradePrice(p1) > TradePrice(p2) THEN

IF Profitto > 0 THEN

LongProfit = LongProfit + Profitto

ELSE

ShortProfit = ShortProfit + Profitto

ENDIF

ELSIF TradePrice(p1) < TradePrice(p2) THEN

IF Profitto < 0 THEN

LongProfit = LongProfit + Profitto

ELSE

ShortProfit = ShortProfit + Profitto

ENDIF

ELSE

LongProfit = LongProfit + (Profitto / 2)

ShortProfit = ShortProfit + (Profitto / 2)

ENDIF

// for LONG trades

Once MinSizeL = 1 //minimum sizecrequired

Once LotSizeL = MinSizeL //starting size (can be bigger than minimum)

Once LotStepL = LL200 //250 //increase/decrease this money step

LotSizeL = max(MinSizeL,MinSizeL + (MinSizeL * round(LongProfit / LotStepL)))

myLotL=LotSizeL

// for SHORT trades

Once MinSizeS = 1 //minimum sizecrequired

Once LotSizeS = MinSizeS //starting size (can be bigger than minimum)

Once LotStepS = LS200 //250 //increase/decrease this money step

LotSizeS = max(MinSizeS,MinSizeS + (MinSizeS * round(ShortProfit / LotStepS)))

myLotS=LotSizeS

if close crosses over average[200,0](close) then

buy myLotL contract at market

elsif close crosses under average[200,0](close) then

sellshort myLotS contract at market

endif

set target pprofit 600

set stop ploss 200

Mine is just the way to split STRATEGYPROFIT into its two components, Short and Long.

You seem to have used it correctly.

many thanks.!!

It seems working well. Maybe I’ll add limits for the quantities.

So you think it’s an interesting snippet for GRAHAL ????
