Change Stop Loss in Strategy

  Hi I am using a strategy to open up to 2 positions and would like to change the stop loss after the price moved 10 point from the entry. In backtesting it seems that it is working however, it doesnt work in real execution. I ran this strategy today and it didnt change the stop loss. Luckily I was in profit and hit the target.

  Does it have anything to do with IG limitation? Is there any work around?

  sl=21
  tp=29

  if countoflongshares<80 and countofshortshares<80 then
  if dhigh(0) – lowest[1]>30 and close[0]>open[1] and dopen(0) – lowest[1]>1 then
  buy 50 contracts at market
  SET STOP LOSS sl
  set target profit tp
  endif
  if highest[1] – dlow(0)>30 and close[0]<open[1] and highest[1] – dopen(0) >1 then
  sellshort 50 contracts at market
  SET STOP LOSS sl
  set target profit tp
  endif
  endif
  if longonmarket and close = tradeprice + 10 then
  set stop loss 0
  elsif longonmarket and close = tradeprice -20 then
  set target profit 0
  endif
  if shortonmarket and close= tradeprice -10 then
  set stop loss 0
  elsif shortonmarket and close= tradeprice +20 then
  set target profit 0
  endif

  set stop loss 0 disables the Stop Loss and set target profit 0 disables the Take Profit.

  Why are you using them?

  Moreover, when accumulating positions TradePrice should be replaced by PositionPrice.

  thanks for your reply, I am trying to change the stop loss to 0 (that means the entry price ) when I am 10 points away from my entry .

  No, to set the stop loss to breakeven you can’t do that, as this will leave your strategy WITHOUT a stop loss.

  You will have to exit using a pending STOP order.

  Thanks, I changed it to the below but it seems that it is still not working:

  f longonmarket and close = positionprice -15 then
  sell countoflongshares contracts at positionprice limit
  endif
  if longonmarket and close = positionprice +12 then
  sell countoflongshares contracts at positionprice stop
  endif
  if shortonmarket and close= positionprice +15 then
  buy countofshortshares contracts at positionprice limit
  endif
  if shortonmarket and close= positionprice -12 then
  buy countofshortshares contracts at positionprice stop
  endif

  this trail works with cumulating positions, but it’s triggered at a % level rather than points – typically 0.2 – 0.3 %.

  a1 and a2 are how fast you want it to trail.

  Sensitivity is a choice of what triggers it – close, high, low or typicalprice (close+high+low)/3

  Sorry, I’m still half asleep – you asked about stop loss, not trailing stop … maybe it’s useful to you anyway.

  Try this one:

  Once Flag1 = 0 Once Flag2 = 0 IF Not OnMarket OR (LongOnMarket AND ShortOnMarket[1]) OR (LongOnMarket[1] AND ShortOnMarket) THEN Flag1 = 0 Flag2 = 0 ENDIF // if longonmarket and close = positionprice -15 THEN Flag1 = 1 endif if longonmarket and close = positionprice +12 then Flag2 = -1 endif if shortonmarket and close = positionprice +15 then Flag1 = 1 endif if shortonmarket and close = positionprice -12 then Flag2 = -1 endif // if LongOnMarket AND Flag1 THEN sell countoflongshares contracts at positionprice limit endif if LongOnMarket AND Flag2 then sell countoflongshares contracts at positionprice stop endif if shortonmarket Flag1 then buy countofshortshares contracts at positionprice limit endif if shortonmarket Flag2 then buy countofshortshares contracts at positionprice stop endif

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

  Once Flag1 = 0 Once Flag2 = 0 IF Not OnMarket OR (LongOnMarket AND ShortOnMarket[1]) OR (LongOnMarket[1] AND ShortOnMarket) THEN    Flag1 = 0    Flag2 = 0 ENDIF // if longonmarket and close = positionprice -15 THEN    Flag1 = 1 endif if longonmarket and close = positionprice +12 then    Flag2 = -1 endif if shortonmarket and close = positionprice +15 then    Flag1 = 1 endif if shortonmarket and close = positionprice -12 then    Flag2 = -1 endif // if LongOnMarket AND Flag1 THEN    sell countoflongshares contracts at positionprice limit endif if LongOnMarket AND Flag2 then    sell countoflongshares contracts at positionprice stop endif if shortonmarket Flag1 then    buy countofshortshares contracts at positionprice limit endif if shortonmarket Flag2 then    buy countofshortshares contracts at positionprice stop endif

  thanks it is working now, however, if I hit the stop or target the order stays open . Is there any command to check at each bar :

  if not onmarket cancel all open orders?

  I think it’s due to close = positionprice, because it’s impossible that a price is equal to another one.

  Try using >= or <=.

  yeah make sense, how about canceling the order after the position is closed? I dont want for the order to stay after  I am not in the market.

  I just read in the other discussion that the Pending orders are cancelled at the end of each bar. Let me explain again what I am looking for:

   

  If long on the market and price moves in my favor by 15 points I want to change the stop loss to the entry to breakeven if the price moved back. If I use the pending order when the first bar closes above the entry + 15 it will create a pending order however , this pending order will be cancelled as soon as price closes between entry and 15 points. So it cannot be used as a stop loss

  Is there any other workaround?

  Thanks for your help .I figured it out.

  Just couples of question , why are you using this: (LongOnMarket AND ShortOnMarket[1]) OR (LongOnMarket[1] AND ShortOnMarket)

   

  and is there any reason that you are using “-1” for flag2?

  (LongOnMarket AND ShortOnMarket[1]) OR (LongOnMarket[1] AND ShortOnMarket) is used to reset some variables when there’s a Stop & Reverse, because Not OnMarket is false in that case,

  “-1” and “1” are used to tell flag2 from flag1.
