Risk based lot sizes
Risk based lot sizes
16 Jan 2014, 17:19
Currently I use MT4 and I'm looking to move to cTrader.
However within MT4 I use a cutsom script that places trades based on stated risk and where I've moved my SL line to on the chart (and limit/stop order if relevant) i.e it places trades at a lot size dependant on my stated risk and SL size.
Is there a way to create the equivalent of the MT4 script (Easy Order) in cTrader if I was to contact a programmer to do this for me?

Yes, a cBot may be coded to create trades based on input such as risk and existing positions stop loss and then stop.
Yes, i definitely need this for my trading on Ctrader. Position Sizing is my most important thing and i miss this function when switching from MT4 to Ctrader. Hope anybody kindly help us in this regard.

Thanks, I would happy to pay someone to code a cBot that can replicate the functions available in the MT4 script detailed in the link below.

Otherwise cTrader is a no go for me.

Do you want the lot calculation or the whole system because with cTrader you can modify the sl/tp by dragging the lines with out scripts. I think I can make a robot to place trades based on that and then you can use cTrader to drag the sl/tp lines or price for pending orders. Let me know if there is something I missed.
Quote from forexfactory:
I made this simple tool to give me the ability to specify sl/tp for new order by using mouse (dragging line object). Input sl/tp manually is a boring task, especially for lazy trader.
It also monitor existing trade sl/tp, which means it will modify existing sl/tp and open price (for pending order) when it detected a different value between order's sl/tp and the corresponding sl/tp line object.
Other feature :
- lot size calculated automatically based on the specified risk.
- a simple popup menu that allows you to quickly close an order based on ticket number
Unlike most line object based trading tools, this program doesn't use EA for monitoring lines object every tick, or a script which uses continuous looping with certain delay. It detects mouse dragging activities (hence why it uses dll) and fire the necessary script. All script will return once its job (opening new order / modifying existing orders) finished.

The lot calculation based on SL/TP via draggable lines.
MT4 also introduced draggable SL/TP once a trade is in play after this script was created, so like cTrader no need to monitor, it's purely for opening a position i.e. I'd need draggable lines on the chart to start with to specify the SL/TP through and then it's case of using the script to open a market order or limit order based on the stated %risk and SL/TP size.
I have a slightly modified version of the original as the original only worked with USD denominated accounts.
Many thanks for your help.

Maybe I'm missing something in the usage or perhaps I don't have the right files. I don't get how the lot size is calculated from the dragable lines. Only the SL and TP are modified if I drag the lines.
This short video should help.
http://screencast.com/t/9I0jlzzleF
1. Drag the EasyOrder script onto the chart.
2. Decide on order type, in this case a Buy Limit - EasyOrder then places 3 lines on the chart, a price line, a SL line and a TP line.
3. You drag the lines to where you want and click submit - EasyOrder then places a Buy Limit at the lot size that is calculated based on the distance between the price line and the SL line and based on the stated risk %.
4. The same is shown for a market order, except this time you of course don't have the price line.
Long after this script was first made, MT4 introduced draggalbe SL and TP lines (once a trade is in play), hence this Easy Order version has been amended to remove it's own SL/TP object lines once the trade is placed (to avoid double lines from EasyOrder and MT4) - so the SL/TP lines you see once the order is placed are MT4 lines (much like cTrader has the same SL/TP lines).
So what I would like is the ability to place trades on the chart through a similar method, a small GUI to state the risk, choose order type and to submit the order request and draggable SL/TP/Price lines.

RE:

It seems I have the wrong files because I cannot move the lines prior to submit. But anyway, I don't think I can code it. I can just calculate the lot based on risk and SL/TP input.
Ok, thanks for looking into it in anycase.

This would be nice if Gold (XAUUSD) is added up as well.

atrader: your cbot is pretty good. Do you have something similar that places pending orders instead of market orders? Would place a pending stop order at the next round 5 pip level. Would actually need two cbots: one for pending buy stop and another one for pending sell stop

No need for two cBots, all you need is add another external parameter, i.e. [Parameter("0:Instant 1:Pending", DefaultValue = 0)] public int OrderType { get; set; }, and then add some logic into the code.
Until cTrader / cAlgo implements a method to Find/Get properties of the ChartObjects, the cBot as per original post (with horizontal line movements) is not easy to do; I guess one needs to have own methods to Find/Get ChartObjects properties.

Wow this bot is good this is something I need. Only needs now is a visible horizontal line for placing stop loss before it gets executed. And a pending order for but stop sell stop too. Please can someone add this to the bot? I really don't know how to code....

Really awesome. What I did is added the bot twice one is to buy and the other is to sell so I just click the right bot to buy or sell. Thank you very much. I really wish the horizontal line option for placing stops would be visible first prior to actually sending the order so that I don't have to use the cross hair to calculate the stop based on pips. Anyway, still awesome bot.Thanks again.

No this is not what I want?..
I want something like where if I tell the system my pending entry stop & stop loss order it will automatically calculate my equity percentage risk and place the order in market on that basis.

RE: Risk management cBot

Have a look at this cBot. Lots to trade 1.0.
Easy to setup and to retrieve information on how many lots to trade according to basic risk management principles.
Free to download here: Lots to trade 1.0
I can't seem to get that from the link. Any chance you have a direct download link!? Thanks

Yes, a cBot may be coded to create trades based on input such as risk and existing positions stop loss and then stop.
