Risk management & trade Size

My mind is getting messed up. Can someone help me how to figure out a trade Size for the following scenario.

I want to Risk only £125.00 for each trade
I will take 2 trades,
Tp1 = R1
TP2 = R3.. so average is R2

I am trying to figure out
a.) trade Size
b.) Stop Loss

For the following which I trade most

1. USTEC
2. US30
3. GBPUSD
4. GBPNZD

You help will be greatly appreciated.
also if you can point me to an idiots guide on how to do this, as in future i want to add gold, oil and btc

The fastest way to get answers to your questions is to open a demo account and place some trades there. You will see all the information you need. Open a 1 lot trade on GBPUSD, put 10 pip stop loss. If the loss is £100 then you know that 1 pip cost £10. Open these trades on all the instruments you need, and you will find out the cost of a pip. Now you can calculate the lot size you need to trade to keep your stop loss below £125.

The first thing will be to determine how much your pip value is for each instrument, some brokers will vary the contract size,GBPUSD, GBPNZD will be expressed in units, however, Indices are traded per contract basis, oil per barrels and Gold per ounces.

For Example, assuming your account is in GBP and you are planning to trade GBPNZD.

0.001(pips) *1000( micro)/194189) (Exchange rate)=0.05 GBP per pip
0.001 (pips) *10,000(mini)/194189(Exchange rate)= 0.51 GBP per pip
0.001 (pips) *100,000(1lot)/194189 (Exchange Rate)=5.51 GBP per pip

125GBP Risk trade /0.05 pip= 2500 pips (0.01)
125GBP Risk trade/0.51 pip = 245 pips (0.10)
125 GBP Risk trade/5.51 pip= 22.68 pips (1)

In every trade setup, you need to identify the price point where the setup is invalidated. Regardless of how much of your account your risk on a particular trade, the reward to risk is always based on the ratio of the profit target to your Stop Loss.
