Grid trading system

hello i want a grid trading system, the strategy is  just as follows:

1. there has to be a signal ( either buy or sell); criteria of buy or sell i will write at the last(for the simplicity purpose).

2. when there is a signal( buy or sell),open a position with 1 lot, take profit is at 10 pips from the entry.

3.if the price moves against the initial order by 20 pips, add  another order with a quantity of one, and continue to do so for every 20 pips movement against the position.

4.take profit: set a take profit for all order at a level where the average price of all open position plus 10 pips would be reached

signal criteria:

sell signal: 1. wma(50) on rsi(14) descending on 15 mins,

2.wma(50) on rsi(3) ascending on 10 mins,

3.wma(50) on close descending on 5 mins,

4. entry when a indicator( i ll give you in private) is greater than 80 on 1 mins.

buy signal: 1. wma(50) on rsi(14) ascending on 15 mins,

2.wma(50) on rsi(3) descending on 10 mins,

3.wma(50) on close ascending on 5 mins,
